Narrowing a rear end

[JamesonRacing]

I have those ET wheels on my 66 Fairlane GTA convertible.  17x7 front/17x8 rear, all with 4" BS.  I had QP make a housing and used early Mustang axles so the rear is 1" narrower on each side.

Wow, a Fairlane like that is what I need to try and talk my wife into for the next car!!

The axles can be cut with a 4 1/2" thin cutoff wheel on a disc grinder... I just did mine. In my case Torqthrust wheels come in two backspacings for 15 x 8 1/2" and the shallower ones make it easy to get the tires in and out compared to the ones with more backspace. But the Strange 31 spline axles I have are too wide for that. They cut easy and the ends of each spline can be beveled with a file or the thin cutoff disc if you are careful.

IMHO for that I would buy a fabbed housing and axles made with the desired offset to handle the chosen brakes.  Currie et al can do these things and you'll have a quality part that drops in.  If those ends are not installed precisely and held during welding and after checked to be sure the welding didn't cause any warping, you will be destroying bearings right and left.  When I upgraded the Mustang, I called Currie and gave them the specs and the car (54" width, 70 Mustang with rear leafs, stock 10x2 drum brakes, small bearing ends).  $400 later I had a housing on the porch, dropped in all the parts (brakes, stock 28 spline axles, 9" center I had ready) and rolled it under the car.
