Is it difficult. I might be swapping my rear end, as I am sick of not being able to get the parts I need for it, and if I can, they cost an arm and a leg. What would I need to do the swap? Do the 9 bolt rear disk brakes work on the 10 bolt? What will I need?

I am not sure on what I am going to do. So depending on how much work it is, I might be interested in doing this swap.

 

I am very happy with my "new" 10 bolt compared to the old 9 bolt, simply because of parts availability.

There isn't anything you need besides tools, everything is pretty staright forward as far as removal and replacing.

for brake transfering the backing plates are different between the 9 and 10 bolts, might have to do a search on that though as I'm not a 100%. I would at least try to find some 89+ PBR brakes though as the previous year brakes are terrible.
