    I bought a 46 Ford coupe and I want to install a 9 inch Ford rear end. What I'm looking for is what width rear end do I put in. The rear end that's in the car is out of a Falcon, which is too narrow.

    Any suggestions?

    My '48 ford had a rear out of a '59 Ford wagon. The car is gone so I don't know the specs. , but it was a perfect fit.

    I just put an 8" in a 40 coupe,
    and a 9" in another 40 coupe.
    Both were from 68 mustangs.
    They fit perfect with junkyard rims.
    The '46 is a bit wider but should be a good fit.

  7. Early bronco is the right width and still has the 5 on 5.5 bolt pattern.
  8. I used a Granada rear, 8", it's 58-59 inches wide. Running a 7" wide rim, everything clears great.

    Thanks for all links to the charts. That will help a great deal.

    I'm a firm believer of placing the tires and wheels you're going to use in the wheel wells exactly where you want them and then sticking a tape measure through one side to the other and make the rear exactly the width you need, or at least you will have an idea what rear end you need...

    Use a 1957-1964 f100 rear. It is exact same width as stock and has 5 on 5.5... 61" if i remember... I just.put one in my 46 coupe.

    By picking a rearend before choosing wheels & tires, you're unnecessarily constraining your wheel & tire options.

    I use a 59 1/2" with a 8" wheel and 255x70 bfg.

    If you are using stock wheels and tires the truck is perfect... Those wide wheels just look dumb on fat fendered Fords... Run 16x4s with 6.00 16s.... Just my opinion.....

    '70 Ford Torino 9" under my '41 Ford. Same as a '46-48. 235/75R15's on rims with 3.5" offset. Tires clear fender lip by about 1".

    I just went to the local Pick A Part and found a 1967 Ford F150 rear end. It is a 9" that measures 61.25 inches drum to drum. A stock 42-48 rear end measures 62.5 so the new 9" is 1.75 narrower. The brakes on older rear ends are narrow and look inefficiant. I pulled the backing plates, brakes, and and drums off a 71 Econoline van and switched them out in the junk yard. The new drums and brakes are much wider with self adjusting brakes. Found two differentials a 2.75 and a 3.25. I'll put the 2.75 in when we go to Bonneville next year.

    I've got an 8.8 rear out of a 95 mustang. Fits great! Had custom rims built for it, to fill the fender well just right.

    Use a 10 bolt Chevy rear and a Chassis Engineering spring kit. Fits perfectly and is the easiest way to go.

    Got a '68 Mustang/Cougar 8" in my '48 Tudor Sedan. Fits like it belongs there.
