I am going to buy an AMC bell pattern TC727 from a 4wd Jeep. My interest is using it as a back up for an AMC Javelin.

I understand that the tailshaft is different, and I've been told that the output shaft is different as well.

I know a little bit about my way around a TF/TC transmission, but what's involved in swapping out the output shaft?
I assume that replacing the tailshaft only involves unbolting the old, and bolting in the new.

Specialized tools required?
full transmission rebuild required?

Thanks,

Steve
