I just pulled the carrier out of my Dana 60RFF I was hoping for 4:10's and got 3:54's.
However I do have a 4:10 gear set for a 60.

My question is will I be able to use the 354 carrier with the 410 gears without a spacer?

I just want to run a welded rear for now to save $$$

I searched a litte more and figuered it out.

It's 4:10 and down and 4:56 and up. In case anyone cares:D

So I can just pop off the 3:54's and install the 4:10's for free. Yay
