Fords were used on the Pre-Alphas,... Back in the 70s.........

You need to know the gear ratio of the drive your looking to buy. Ford V-8 is not enough information to go on. Can you get the serial numbers off the drive?

Sellers will say anything to relieve you from your money. If it was Ford, it was 77 or earlier, and the one drives weren't as heavy duty as your Alpha I.
Get the right thing, don't be going backwards. You would also have to change the shaft that goes into the coupler. Different sizes on Ford and Chevy V8's
If your present drive is good, and the drive you was using before the engine problem, why replace it now?
