Hi Guys, I am new on here, I have a 91 non intercooled 12v, I am going to fit a 2nd gen Intercooler to the truck, then do some engine mods to achieve around 300 hp, but the intercooler is first, any help is greatly appreciated...Thanks

the gear I am talking about is on the output shaft, you have to pull the driveshaft, then the yoke, then the end housing that the speedometer gears are in
Ahh that makes more sense. Let us know if the new gear fixes it!!!!
