AUTOMATIC TRANSMISSION SWAP FROM 83 TO 85

1985 Mazda RX7 • 4 cylinder Manual •

I am taking the automatic transmission from an 83 Mazda RX7 and putting it in my 85 manual RX7. I am using the rear eccentric shaft counter balance from the 83. Do I have to use the 83 front balance weight? Mazdatrix show the same part # for the 83-85 aft Both cars have 12A engines. I am installing the automatic transmission from the 83 to the 85. The 85 has a manual transmission.

From what I know, the aft eccentrics need to be for/from the corresponding type of transmission. The front balance is normally matched to the engine.
