    With a 8" lift in a k5 you need to drop the t-case at least 2" and shim the axle atleast 8 degrees to keep driveline vibs down. Also put a part time kit in your 203 because it will throw the front angle off really bad when you lower the t-case that much. If I were you I would do a 6" lift and either cut the fenders to make the tires fit or do a 1-2" body lift. BTW you need to lengthen both driveshafts. You will also need a drop pitman arm, steering arm and possibly a drop center link. You dont need all of that for a 6" though just a steering arm and possibly a center link.

    You can try an inch. Just take the spacers that came on the truck from the factory and put them inbetween the frame and the crossmember. The spacers are either on top of the frme or under the crossmember.
