Putting in a posi unit is something you can easily do yourself with very few specialized tools that you can either borrow or buy for much less than what a shop would charge to install it. You dont have to set the pinion depth since it is already set . All you have to set is gear backlash and the only thing you need to set that with is a dial indicator and mag bas. $45 or less for an economy set from J&L industrial or harbor freight for that matter. If you have even the slightest amount of mechanical aptitude you can do it on your own. I did my first posi install when I was 14 with no help. You have a thousand years worth of experience right here on this board to help you. Go for it.

Also, I'd get some "pression blue" (sp*) from your local parts store. It's a dark blue grease, kinda like acrylic art paint that you put on about 10 teeth on the ring gear to look at your tooth contact pattern. turn the ring gear a couple of times and the pattern will show up in the blue.

while double checking isnt a bad idea its really not necessary to check the pattern with prussian blue or good old white lead on a simple carrier change. Your'e not modifying the pinion depth in any way by changing the differential assembly so your pattern isnt going to change.
Its the backlash that will be affected in such a change and you will need a dial indicator with some means of mounting it such as a mag base in order to check and adjust the backlash.
