    WTB cobra/ thunderbird/ explorer 8.8 IRS pumpkin - possibly axles

    I'd like to find an aluminum center section, and possibly axles from above mentioned vehicles. Looking at doing a conversion this winter, and I'd like to have one to play with.

    I'll also need the cover off an explorer diff, as it has the mounting capability that I need. I'll probably start looking at salvage yards, but I'd rather buy it from someone who can tell me something about it.

    Thanks!

    I think Joe has a complete rear end out of a Mark VIII that he is trying to sell. I am not sure if its the same or not . . . .

    Its possible. I'd prefer an aluminum case though, but if its cheap, it could be an option.

    Mark VIII and Thunderbird are likely cast and not aluminum and are only 28 spline but I've seen them used on Monster Miatas with LS1's so they must be fairly decent.

    Joe's is cast. I think he kinda wants a lot for it too last I asked. I can ask him tomorrow when I call him to set up doing my swing out kit.

    are the aluminum ones strong enough? my solid rear came from a thunderbird turbo coupe , 1988 maybe. had 3.55 gears which is what i wanted. spend the extra money and get a clean one.. mine was sitting for like 7 years and it was nasty inside, the gears were borderline with some mild pitting but i decided to use them anyway.

    how much power can that irs setups hold reliably ?
