Bill,

According to "MazdaTrix" the 86-88 an 89-91 front counterweight= s are different stock numbers

and I am sure slightly different weight to balance lighter 89-91 rotor= s.............IMHO

Gang,

Does anyone have a rea= r counterweight off a '91-'92 13B NA automatic? I am rebuilding my '8= 6-'88 13B with the lighter 9.7-1 rotors from a 1991 13B NA, but it had a ma= nual tranny. The part numbers are the same for the front weight, but = not the rear one, so I need to find a rear weight.

Any other problem= s I might run into?
