Lots of people have posted mini-tub installs. Here is my version done in my garage. Scroll to the bottom of page 2 for the start. There are a few useful photos in there.

Also, I really like the DSE website. You can browse all their old projects and see how they do things and you know it will be done correctly. More-or-less the same process with any mini-tub. Make sure you know which rear suspension you are using before you start. For example the DSE quadralink has a cross-member that ties into the tubs and it is easier to do both at the same time. I made the rookie mistake of drilling a bunch of spot welds I didn't need to. So watch how people cut things out and choose the most efficient way to avoid extra drilling. It is a straight-forward and rewarding job but expect to take a while your first time. Also there is a photo tax. You have to post lots of photos as you go along - welcome !
