I don't know what an MIT/3512A055 is but it doesn't matter. Anytime doing rear differential work you want the gears set back to factory specs not how they are now. Unless you have measuring tools and knowledge, you need to send this work out.

I have got a quote from Jacks to do it for $1450, and I thought it's just direct swap and go, buying the parts only can save some money, but it seems really involved, and it looks like I'll pay the $1450 for the right thing
Thank you for the response

Does it have an instruction of how to do it, I have not done a proper google search on the topic yet, but is it tricky as far where everything goes ?

Well here’s what needs to happen. You need to set the gear pattern first. Pinion depth and ring gear side to side determine how the gear teeeth mesh. Like I said google it and they have pictures that will show you where to add and remove shims to shift the pattern around. I always start out with the original shims and that usually gets you pretty close. You will need an indicator to set the backlash as well. Once you have the backlash and pattern where you want it then it’s time to set your bearing preloads. On the pinion you just keep tightening the pinion nut until you get the desired preload on the bearings. Lots of old school guys do it by feel but you’ll need an inch pounds torque wrench to set it correctly. The carrier uses shims behind the bearing races, you’ll already have some behind the races from setting the pattern. Now your going to add equal amounts of shims to each side of the carrier to get preload on the bearings. I’m not sure how mitsubishi tells you to do this, sometimes it’s an added measurement of shims from zero preload, sometimes it’s rotational force on the pinion nut in addition to the pinion preload already set. When I put the Kaaz posi in my ride I need to change nothing, the pattern looked fine and preload on the carrier still was tight, didn’t even change one shim.
The first time you do it will be tough after that it will seem easy.
