    A ford 8" rear end found in 75-80 ford granadas and mercury monarchs usually fit up perfectly for a model a. I'm not sure but I want to say they are 58.5 inches wide drum to drum total.

    Here's a link with some common rear end lengths for reference.

    A V8 Maverick rear end is 56 inches wide........
    measured from wheel mounting flange to wheel mounting flange.

    Works out perfect under a fendered Model A sedan....

    The Granada 8.8 rear ends are 50" between the backing plates.

  8. if you are going full fendered and want to keep the tires inside the fenders , go with the maverick 8" rear...as previously stated , 56" wheel mounting flange to wheel mounting flange

    measuremants of backing plate to backing plate means nothing
     
  9. It depends whether you're going to channel the car down to the earth or run it high enough to cover the tires with fenders!

    Also depends on the wheels and the offset at your desired driving height.

    The 56 inch to 58 inch should work fine for a Fendered car (again depending on the Wheel/Tire combo) but a much wider axle would be needed for a severely channelled sedan... otherwise you'll be looking around for spacers so that the tires clear the body.

    In other words find the wheel/tire combo you want to run and determine where you want the ride height and measure the distance between the wheel flanges and then find the appropriate rear end with the width that'll work...!!!

    Good Luck

    One thing gone un-addressed so far is the necessity to push in the inner fender panels to allow for the installation of all but the widest of rears. I narrowed a Ford truck 9" rear to 55" for my installation. If I were to do it again I'd do 56". Bitchin makes a nice set of easily installed wheel tub style inner fender panels for your Tudor.

    Well perhaps something.

    Use the following information to gauge full width when given backing plate measurements.

    Face of axle housing flange to wheel mounting flange is as follows:
    Older 9" Ford 2.36" per side
    Newer 9" Ford 2.50" per side
    8" Ford 2.66" per side
    Figure about 1/8" for backing plate.

    Are you working tighter than this? Regards, Ron
     
  13. A 1985 Chev S10 2-wheel drive rear axle is the correct width with no modification, and running stock Chev 15" wheels it fits perfect in a full fendered model A Ford. The slanted spring pads are a puke, they will have to be torched off and replaced. I am running one in my model A roadster pickup.

    My rear is an 8" froma 68 mustang. I thought of getting a wider rear end but I hated the way they look when they are too wide as opposed to being tucked in close to the body. I cut a new radius around the tire and pushed this in and flattened it out and recreated the wheel opening that way. I think it turned out all right. I cannot recall what the dimensions were of the axle.

    iam running the rear off a 53 ford. fits good just need a little offset on the rims right now theres a 1/4 gap between the sidewall and body but it all depends on what ya running for a motor too a 53 rear won't hold up to a high horsepower motor but it should work for the 53 flattie it was bolted to from ford. for the most part the granadas and maverics are the most common for what is said to use.

    I have to agree. I have an 88 S-10 rear under my 31 coupe, with no mods at all. I'm running 10"x15" aluminum slots and 11" wide glass fenders. Looks right and no clearance issues.
