    I was looking at the sidewinder kits offered at www.proficientperformance.com
    they list different kits for '82-'87 or '91 2wd and basically the same years 4wd trucks. with a $100 difference. I didn't know there was a difference in the 2wd/4wd versions, anyone know if there is? I could see a longer exaust needed on a 4 door but thats not what they're showing.

    I'm guessing but I bet the crossover exhaust pipe from the drivers (stock) manifold to the Banks manifold is different to clear the different crossmembers. I bought an old ATS turbo kit (looks very much like the Banks) and now I find out it must have been for a 2WD :doah: Guess I be getting real friendly with the local custom exhaust shop :rolleyes:

    I think they're referring to "C" code and "J" code motors. "C" code had the ugly EGR valve in the middle of the intake manifold. "J" code came on the 3/4 & 1 tons IIRC. I don't know of any other difference between the heavier trucks.

    thats the weird thing though, they are listed as 1/2-3/4 under one and 1 ton under the other. then theres a heavy duty and light duty version of each. that means theres 8 kits:eek1: 4 for 2wd and 4 for 4wd
