Rear end
Ok I did a search, but couldn't find my answer after looking through a few pages of results. I know I saw this before, but couldn't find it. When getting parts for the 9.75 their is a dana model that is similar right? I think that was only for the rear cover though. Also would it be possible to change out my open diff with a limited slip without having to have a pro do it? I'm asking because I wouldn't be removing the pinion gear just moving the ring gear to the new l/s diff. Also does the 9.75 use c-clip's, and if so would you recommend a c-clip eliminator or no? I know when I had my mustang the word on the c-clip eliminators is they are pretty much junk. Well thanks for any help.

Yes, the 9.75 is a c-clip axle. Can't speak for any Dana cross-compatability, but I would highly doubt it.
To swap diffs, you'd still need to have someplace re-shim the carrier. You won't need to re-set the pinion depth unless you change ring gears.

I switched my open 8.8 for limited slip on my own. You do have to shim it out when you put the new carrier in. It's time consuming and can be very frustrating and confusing to somebody who's never done it before. I borrowed a dial indicator from a friend, although I think you can buy one for around $30. If you are going to attempt it on your own I would recommend that you thoroughly research it and take your time. I don't know if you've had any experience with rearends, but if not it will start to come to you once you start shimming it out and everyting. When you are putting the ring gear on, work very carefully so that it goes on completely straight.
If you have ABS, you will probably need a torch to get the ABS gear on the new carrier. I did not put mine back on because my ABS didn't work properly anyway and I didn't feel like messing around with a torch. If you don't have access to a lift, it may be a good idea to drop the whole rear axle assembly. It's much easier to work on it on a table in the shade than have two people struggling for space underneath the truck. You will need a helper when putting in the shims.
If you have any questions, feel free to ask. I am by no means an expert but I have done exactly what you want to do so I kinda know where you're coming from.
