Well, as some of you know, I've been looking to change the final drive ratio on my base Deville ('91) to that of the '91-'93 Deville Touring Sedan.
Seeing that both are 4T60-E's and 4.9's, I assume that I shouldn't need to many parts. Rockauto has the final drive gear for the touring sedan, but I feel like I would need something more.
Would the final drive gear be all I'd need? Or would the change require something more?
Thanks in Advance.
