Transmission Swap ?

WE3RX7 · 01-11-2009, 08:53 PM

I'm 99.9% sure that a 12A trans from an '84 FB will bolt up to a GSL-SE 13B. I know the driveshafts interchange, the bolt pattern is the same, etc so I'm pretty clear on all that.

What I'm not clear on, if using a 12A transmission (5spd) on a 13B GSLSE, which flywheel do you need to use - the 13B one right? I cant recall if the splines on the clutch/flywheel assembly from a 13B work with the input shaft on the 12A trans and I dont have the parts here to check..

Any insight would be appreciated... thanks.
