When I get home I will try and post a couple of links I have bookmarked. I'm working from my phone right now. Liked SS said it is hard to do a perfect job like a professioal shop can do, but I have done my own over the years with no issues at all.
If you do decide to do it you should take the time to study up on it and ask lots of questions before tackling it. It can be done with the right approach.
The only other option is to have someone do it for you, the last time I had one done it was 12 hundred to set up a Dana because I needed it in a hurry. That was
ten years ago.
