Is an 8-1/4" rearend the same for all years?

Not sure if the parts swap will work, but before you take it apart the chief mechanic over here says you should measure the back lash of the ring and pinion and make sure it is the same when you put it in the next rear or you will have a gear whine.

Try Richmond Gear to get the tech info you need. They should be able to help.

You could also contact [email protected]. Cass was recommended to me by someone on FABO and he was a tremendous help in getting the right parts for the 8 3/4 in my Dart. He most likely knows about the 8 1/4 too.

Good luck!
