Ok, so as you can see, I'm new to this forum and that's because I just got a "new" truck. I'm trying to make it inspection worthy and issue #1 is the tag lights. They are the bayonet style kind for step bumpers and the ones that were on the truck were rusted and dirty and one was missing a connector, so I got brand new assemblies made by "HELP!" But, as best as I can tell, the old assemblies were held on by rust/dirt because they were just stuck there and after removing the cover I popped them loose. The new assemblies won't stay on, and I even tried puting the backplate behind the bumper and screwing the cover on which was ridiculously complicated, didn't look right and I could only get the top screw in a thread or tow and then it would pop loose.

So, how are these supposed to hold on to the bumper? I'm considering just getting some bolts and nuts and reengineering the thing, but is there a proper way it should be done?

 

Edit: I made a somewhat to scale drawing trying to show the relative size of the screws vs. the cover, the back plate and the hold in the bumper. Please not the bumber hole is not tapped.

They screw in, as you mentioned. If it is that rusted or the holes are stripped out, just bolt them in.

 

Well, there are no screw holes, it's just a hole that about 1/4" that allows the cover screw to go through. Maybe something has been changed from factory, but seeing as this truck is 25+ years old, it wouldn't suprise me.

Have you tried this type of light? It just pops in the hole.

 

The hole is too big. I have a friend with an 84 C 20 and that's what his bumper will take. I ended up just running a bolt and nut through it. I would like to more make the cover to come off without the backplate, but for now that shouldn't be an issue when it's inspected.

      Towing In Loose Gravel

      Very true.   However.  GM did give those trucks with the single speed case Terrain Mode.  Terrain Mode mimics 4LO minus the gear reduction and torque capability.  It uses the ABS/braking system to perform the operation.  It also gives these one pedal driving (sort of) when in Terrain Mode via the active brake during throttle lift.     Does it have its limitations over a true 2 speed case?  Sure.  But it works.

      Of course actually engaging four wheel drive is step one or even daring to use a ramp like that with a two wheel drive and getting into a mess because of it. As to 4 low, these last few years if its a GM half ton it may not even have low range. A lot of the newer pickups have a lot lower first gear in an automatic transmission then they once did as it was common at one time for a gas engine truck or even the older diesels to just sit there and bog the engine due to the torque converter stall point and not enough torque was generated on reasonable traction to even spin a tire or get out of its own way up a steep grade and 4 low HAD to be used to get enough power to four tires to get them turning. These days traction control systems may hinder a vehicle in a situation like that although that means a tire or tires are spinning so in some ways the traction control can reduce wild spinning and anyone can correct me on that but I think some vehicles cut traction control off in low range ?.    By the sounds of it and you may have the proper equipment but if your responsible for helping vehicles out if they are not able to get out under their own power, I would say to be using a nylon tow rope or have one available so that one is able to give a bit of a run to help sling shot them some initial momentum as most tow straps are made out of polypropylene and impart way too much shock load if used to jerk a stuck vehicle into motion but are totally fine to use if going more from almost a dead pull with the tow vehicle and they are a lot less expensive to replace if damaged. That and some soft shackles to hook onto closed loop tow hooks on the truck your pulling as well as you having the proper shackle insert in your truck so there are no bad accidents with metal clevises joining things together or chain on the end of a tow rope or tow balls being hooked onto etc flying and causing damage or worse if it lets go. Its always a challenge pulling people because some are clueless and will over run the tow rope or strap and drive over it or that risk of ramming into the back of the tow vehicle so usually a few instructions are needed to clue in the driver of the stuck truck. Yeah ... have fun out there 😉

      OCI, not when but why?

      In their own words:    https://blog.amsoil.com/how-engine-sludge-forms-and-how-to-prevent-it-2/   [Quote] Synthetic Oil Helps Prevent Sludge Fortunately, sludge and varnish deposits are something that can be controlled. Using thermally stable synthetic base oils reduces the rate of degradation (oxidation).   Antioxidant additives further help reduce the rate of degradation. One of the most widely used is zinc dithiophosphate. Not only is it an excellent oxidation inhibitor, but it is also an outstanding anti-wear additive.   High-Quality Additives Fight Sludge Fortunately, it is possible to address many of the issues that occur after the initial oxidation stage. Additives, such as detergents and dispersants, help promote the suspension of contaminants within the oil and keep them from agglomerating.   Detergents, which are also alkaline in nature, assist in neutralizing acids generated in the sludge-building process. Antioxidant, dispersant and detergent additives are consumed during use.   To achieve maximum life expectancy, use a motor oil with high concentrations of antioxidant, dispersant and detergent additives.  [End Quote]   So quality base oil and then the last sentence above. TBN and ZDP levels matter. The one thing not covered was sufficient viscosity. Sad.     And yet we now have since API SN lower amount of them all with the only real change being a slight up tick in base oil selection. Along with lower concentrations of everything that makes oil work and lower and lower viscosity there is still an insistence on longer OCI's.    How low does the peanut butter and jelly level have to get before we say it's just white bread folded?    The new smoke and mirror treatment is the 'additives are INVISIBLE' to UOA testing with a health dose of TRUST ME.    I'm not picking on AMSOIL. This is coming from all of them. Every last one of them that abandon the low wear model in favor of the high mpg/EPA compliance model.

      First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move.

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.
