Gang,

Does anyone have a rear counterweight off a '91-'92 13= B NA automatic?  I am rebuilding my '86-'88 13B with the light= er 9.7-1 rotors from a 1991 13B NA, but it had a manual tranny.  The p= art numbers are the same for the front weight, but not the rear one, so I n= eed to find a rear weight.

Any other problems I might run into?
