Early 23 spline? All big blocks 4 speeds other than the hemi trans were 23 spline.. Its a 70-74 trans from what I was told. It has both the B and E body shifter mount.
I have a B/E a-833 4 speed to sell. Comes with trans, hayes flywheel, older Lakewood scatter shield, block saver plate, hurst comp plus shifter with a couple different sticks, fairly new throw out bearing. misc clutch parts. asking 900 plus shipping or.. worked good when removed from my 63...
After about 12 years sitting in the corner of the shop it lives again!! still has a long ways to go to be driveable but its a step closer, a big step!
