My 63 rear end ratio is an open 3.24.
Would it be worth the work to install a 3.08 posi, which I already have?
Also, would it require changing the trans speedometer gear? Thanks, Ed

A 3.24 ratio was not offered in 1963. Available ratios jumped from 3.08 to 3.36.

IMO the 3.08 would be a worthwhile swap if you want taller gearing and/or posi. If you want the speedo to read accurately you would also need to change the speedo driven gear in the trans.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.
