As it says, i know what to do as far as the install goes, I just would like a link if possible with pics to have a better idea or some sort of write-up.... Ive searched and only come up with differences and opinions about the 3.90 and 4.33. Also what the best place to get them?

Thanks

You can get them here:

I would recommend taking them to a qualified mechanic to have them installed. I would recommend that you do the R&R for the diff as they will save quite a bit of money.

Thanks, Im qualified to do the work, i just want to have an idea on these cars, although i dont think there should be difference since all rear ends are pretty straight foward....

No offense, but if you were qualified you wouldn't be asking for a write-up on how to do it. The FSM in section M describes the assembly process of the diff. You'll need the correct shims for the 4.33 ring & pinion as well as making sure you have the proper teeth depth of the gears.

You'll also need a crush sleeve, as well as side oil seals. Call Ray Crowe at Malloy Mazda for all your OEM parts needs at 888 533 3400, he owns an FD so you don't need part #s, you can just describe to him what you're doing and what you need
