Torsen differential upgrade in a 97 c1500

Hey there all

 

I've done as much digging on my own before coming here but Im needing some help. I currently have a 1997 Chevrolet c1500 extended cab, my RPO code tells me that i have a factory GU8 rear differential and I'm looking to upgrade. I've always been weary of clutch style lsd differentials so I've been pouring over information on torque sensing positrac diffs. I think I've come down to my final run down on what I'm wanting to do but I want to get some feedback before I spend the money 

 

From what I can gather, the rear axle  under the 98-2001 Camaro is the same series as the axle under my truck, and I believe has the zexel t2 series torsen differential I'm looking for. So I'm hoping that I can take the zexel from a Camaro and mate my current ring gear to it to use in my truck. If anyone has any more Info I'd be really appreciative.

GM had varying sizes on 10 bolts but if you can match up an axle I don't see why not. The Torsion diffs are cool. I have considered swapping the Gov bomb a few times myself. 

Only issue might be spline count from a car with 5 lugs to a GM truck with 6 lugs. Little research on the car side and you may have that figured out.

 

Maybe something like this:

I think a lot of cars got a 7.5 Diff and trucks had 8.6

My truck is only a half ton with the 5 lug pattern. I haven't had much time working with Camaros from the late 90's so I haven't been inside them much. But as for the gear count that's why I was planning on mating my current ring gear to the new differential.

Many of the V8 cars had them, If you find one with the same sized axle you can bolt your gears onto the diff and rock it. Would make for a good diff and a cheaper price tag. The aftermarket diffs get a bit pricey.

      Compare 2016 SLT Bose to 2020 Denali or AT4 Bose
      By SHEVLINI
      Anyone updated a 2016 Sierra to 2020 Sierra (Bose 7 speaker on both?) I am looking to update my 2016 SLT crew to a 2020 Denali, and want to confirm I am dealing with the same (or similar) animal.  The 2016 has PAC AP4-GM61,  old school PPI PC450 running 100x4 at 2 ohm, Infinity Kappa 60CSX component front, 62IX 2 way rear, Rockford Fosgate R500X1D running 500 watts at 2 ohms, and a sealed JL 10w1v3-4.  Embarrassed to say factory dash speakers, but you do not hear them except for a phone call... Incredible sounding system, but I do not want to have to do it again. Does 2020+ no longer use "MOST" bus communication? Anyone measure wattage from Bose?  Any difference between SLT, AT4, and Denali Bose amps?  Thanks in advance for your research assistance.

      Wanting to upgrade to heated tow mirrors, need some help
      By Nathan m
      I have a 09 silverado 1500 WT 
       
      It has heated rear window but no heated mirrors. And I can't see a wire for heated mirrors in the door compartment (although I haven't opened the door panels in a few months) I do seem to have 2 wires (it feels like 2) going through the door boot (I haven't opened the boot to see the colors but I assume it is for the door open sensor, but I could be wrong)
       
       
       
      I am wanting to add tow mirrors to the truck and especially heated mirrors ( I plow with the truck and really would love the heated mirrors) I was wondering how I would go about adding heated mirrors ( like I said I have the heated back glass so shouldn't the wiring for heated mirrors already be in the truck as I think they run off the same switch and I'm gonna assume the same harness ( I could be completely wrong and they could be different harnesses)
       
      Looking for help as I am wanting to do this conversion if possible

      150 watt inverter upgrade to 400 watt
      By cprime
      My 2018 GMC sierra has a 150 watt inviter. I've hear the newer trucks with the plug in the cab and the box have 400 watt inverters. Anyone try to upgrade or retrofit these inverters into an older truck? I'm looking for a little more power and so far this is how I want to go about it instead of installing a separate inverter.
