    Sorry for the off topic post but I need to find a rear diff pumpkin for a 77 Mustang II quick and was wondering what all will fit. I'm sure this group can answer quicker than me trying to figure out where to ask (there probably is a Mustang II forum somewhere) You can PM me or post if here if everybody doesn't get too riled up about it.

    It's a Ford 8", they are fairly common. Oddly enough, a LOT of MII's got 3.40:1 posi pigs from the factory. :D FYI its 57.25" flange to flange overall width, 4-lug axles. Fits nicely under an early Mustang too. :D

    Is the bolt pattern the same as early Mustang / Falcon six cyl (4 x 4 1/2?)

    All Mustang II were 4 lug cars. If you wanted you could use the Maverick 4 lug 8" rear.
     
  11. Do you just need the center section?

    Thanks,

    Yea, just that part. The car will be getting a 302 in it and I was wondering what I might find used cheap.

    One other question, can it be flat towed without it? I assume not since nothing is supporting the end of the axles.
     
  13. No, but the good news is they are REALLY easy to drill because if you pop out the other 3 lugs, the remaining one is where it needs to be for the 5 lugs. Mic off the center and go.

    8 inch...........I took a 3:55 center from a Mustang II and used it in a Maverick 8 inch in my Studebaker.
     
  15. I believe any Ford 8" center section should work. I'd go to a self-serve junkyard and get a whole rear end. Also, post a wanted ad here. How far are you from FlatTopBob's yard? If you're looking for a "posi", you might see what a new one costs.

    Thanks,
    Kurt
