If the Safe-T-Track unit is same series as the open one (1,2,3) then swapping the ring gear over and same shims it had should line up very good usually but regardless the backless should be measured before and after to compare and the preload remaining. But again also just swapping whole sub B ain't bad either. You could clean paint whole other one nice in advance.

The 1966 Pontiac Chassis Shop Manual states "The Safe-T-Track differential is similar to and interchangeable with the standard differential case assembly (the ring gear and side bearings are identical)".
From a practical standpoint are there any issues of which I should be aware before attempting to swap the differentials? I could of course simply swap the rear axles but would prefer not to do so unless there are good reasons.
Axle ratio not an issue for this swap.
