you might wish to use the right bolts, and may need to replace the nuts, if you prefer the seat stays in place in the event of a collision. -

The proper socket for them is e-torx And yes, they go through to the underside of the body, so it's better if you clean off the parts sticking out as best you can prior to removing them, to reduce the chance of wrecking the nut welded to the cab, as it sucks to weld a new one to it.

Did it ever work for you, or has it been dead the whole time?

197,500 Road Trip 9/1/2026 Did the 325 mile round trip to Hoerr Racing (Red Line Products Distributor) to pick up a few cases of select products I like. It was a blister today. 92 F when I left and 98 F when I came back with heat indexes running 103 to 110 F. Machines don't really care about nor are strained by the Heat Index directly but humans are, and I be one. That meant the AC was in service all day and THAT put a load on the system it does care about. Peak 98 F, Index 110 F, Oil temp 208 F, ATF temp 180 F, water 182-188 F. Road speed 60 mph. Wind 6 to 10 from the SSW. Trip runs all four directions. Long pulls 5 to 7% grades up and out of the Illinois River basin. The Mobil 1 Euro 0W40 is telling on itself with oil temps that high at that speed. The Red Line runs 197-202 F. But it is a PAO majority lubricant and that is one of the features of that base oil is its excellent heat absorption and rejection properties. [AMSOIL is up next] Filled at both ends of the trip and using the odometer and pump she netted 20.22 mpg on 75% Ethanol. Color me impressed. https://www.fueleconomy.gov/feg/PowerSearch.do?action=noform&path=1&year1=2014&year2=2017&make=Chevrolet&baseModel=Silverado&srchtyp=ymm&pageno=1&rowLimit=50 EPA list it at 16 mpg highway on E-85 and 24 mpg on regular 87 octane. Locally in mixed driving it has been delivering about 18.6 mpg. So Pepper with just short of 200K on the clock is giving 25% better fuel economy on the highway and 33% better in mixed driving. While on SAE *W40 oil with the AC on??? Fuelly.Com doesn't have any trucks of my spec on E85 but it has a bunch on gasoline and in practice they get the same mileage on gasoline Pepper does on E85 (@75%). 😱
