got the newer style engine sitting around? if so, unbolt the accessories and if the heads and block have the same bolt holes..... your 92 aluminum accesorry bracket will bolt up to the newer motor..... use ALL your old accessories and save any head aches.
if your trying to use the new brackets, you might be asking for trouble, although i might be wrong
chances are if they changed things, they will be easily noticable changes
Yesm the accessories are the same.... I had the waterpump, power steering and AC on my 92 VIN W (same engine in the 95) from a 99 jimmy... They're the same... Actually the only difference was that the PS pump had the extra long filler neck for the PS
