well, the weather finally gave me an opportunity to get out and get stuff done. Last week I got the rear axle housing back from being narrowed. I took a Ford 7.5" axle from under a Ranger and had the long side narrowed to match the short side. Then got an extra short axle and now the axle will fit under the GT. I also scored a limited slip carrier from a Bronco II. I got the complete disc brake set-up from a Mustang with a 7.5 and fitted it to the Ranger axle housing. Here's how it went together....
Limited slip unit from the Bronco II..
These caliper brackets from the Mustang were originally mounted to the outside of the axle flange, when putting on the axle for the MG swap, they need to be cut so that they will bolt onto the back face of the axle housing flange...
like this.
next goes the brake backing plate...
and the rotor.
then bolt on the caliper slide bracket using shims to center the rotor in the opening..the washer is just stuck in there trying to get the spacing right..It will be replaced with a shim in the final assembly.
Then mount the caliper....and the anti-moan bracket that straps to the housing to strengthen the mounting. One other bonus is these calipers have an integral parking brake.
and you've got a 7.5 Ford rear end with limited slip and disc brakes that will fit under the MGB GT! Now to take it all back apart for clean up and painting before final assembly.

Also sourced a Buick 300 water pump that I've been needing and when I looked at it compared it to the Rover pump, I realized it wasn't even close. It seems I had a timing cover that was only used a year or two on some Rovers and would put the water pump up too high. So after a brief search, found a Buick V6 timing cover that was just what I needed. Now to get the gaskets and put all this together.
Well, the weather has not been cooperative of late, so not a lot of work haqs been done to the bodyshell. I have picked up a few pieces here and there. I got a cooling fan and relay module from a Volvo 960, nice and thin, good sized fan. Got the Ford 7.5" rear axle housing back today from getting narrowed. It looks great, I'll post some pics tomorrow. I did learn one thing in gathering parts for the rear end...There are two different length "short side" axles from a 7.5" axle. Apparently the drum brake axles are a different length than a disc brake axle. I grabbed both my "short side" axles and took them to the guy that was narrowing my axle and noticed that they were not the same. IIRC, I got the second short axle from the Mustang 7.5" rear when I was getting all the disc brake parts. So now I need another Ranger axle. The difference is fairly small, the Ranger axle (drum brakes) is 26 3/8" whereas the Mustang axle(disc brakes) is 27 5/16.
