[EM-EFER]

I want to put 3.9 Final drive ring and pinion in my 350. I just don't want to get raped by a dealer/our local speed shop to install. Any shops near Albany NY that could do it on here??

Would be easier (although more $$) to just purchase a complete assembled rear diff w/ 3.917 (and LSD if you want).

That way it would be easier for you to find a shop that can just swap pumpkins (rear dff) rather than have them need the special tools to just install the 3.917..

That is what i'm doing.
