apart from the body kit ie body, front block, back block, the only part that is a different size is the bolt
almost right, but not quite.
you will also need a new semiblock screw as the pre-2k ones are smaller.
and as you'ver been told, a new bolt.
also, its likely u dont have a standard velosity adjuster in there, so the new body will need a hole or 2 drilled.
all the other parts are tranferable, but, unless its been serviced in the last few years, you need a few seals and springs as well while you are at it.
also, unless you are VERY up on your cocker teching, changeing a body oper isnt something you want to do yourself
hope this helps
