Thought I'd throw in my 2 cents on the discussion below as it pertains to the 57-59 Ford rear ends. I just went through one of these before I put it under my Cobra. The 1/4" per side diffrence on the spring perch is no big deal. The rearend I have, (and I think all of them in that era) has manual adjusters, again no big deal. I was going to change to later backing plates and drums. Unfortunatly these rear ends have a small flange on the axel housing and a lot of the latter backing plates wont fit. I ended up using the original backing plates and found a virgin set of brake drums. All the parts I needed for this rear end are still available (wheel bearings, brake shoes, wheel cyls etc.) Depending on the 3rd member you use you may have to drill and tap the boss on the third member as there is no fill hole on the housing. As far as brake bias, I think I'm using 7/8" wheel cys. With the tire combination I'm running (295/50 15s rear and 185/75 14s front) the car stops great with neither end locking up before the other. If your rears are locking up before the fronts, you might try wheel cyls with a small inside diameter to reduce the amount of force to the rear brake shoes, or adding an adjustable proprortinig valve. Overall these are a good 9" for the Mustang IIs, but hard to find. The only major problem is availability of brake drums. If I ever get to the point of needing to repace drums in the future, I will proably use one of the kits to convert the rear to Disk brakes.

I have heard that the 65 and newer are stronger.

Actually the 3rd Member in a lot of the 59s were the very desirable N cases (Nodular) which will take more abuse than the later third members. Any 9" third member will fit the housing (I'm running a 63 T Brid unit currently). The down side is the axels are 28 spline and smaller diameter than the later units. The axel in my Cobra saw prior duty in 2 street/strip 351W Pintos with no problems (other than a couple of broken 3rd members) over a 20 year period. Ahh my misspent youth.

If you go to NAPA they can look up a van 60's the has the same size drums and then you can get all the auto adjuster parts from that. I did, I am using the same rear, and rebuilt a set of 69 full size wagon brakes (10"x2.5) before realizing they wouldn't fit. I got the auto adjuster parts and just used those with the Granada retro-fit rotors on the front and she stops GOOD.
