Just to clarify, my C56 came from an AE101 20 valve Levin. So what I had to do may not apply to other C56 boxes from other cars.

I had to drill and tap holes into the C56 centre casing for the end gear box mount. The casting was already thickened up in that area so it was easy to do on a drill press.

The selector lever on the C56 was also different and as the Echo cables don't have any provision for adjustment, that had to be modified as well as the C150 selector didn't work int he C56 box.

Thanks for sharing your setup! I've been thinking of doing the same thing, but there's a bit of calculus involved: you have to be able to account for the mass of the bar and axle socket and how it changes the load. My plan was to use a small wooden dowel and a calibrated weight from a balance style scale, but the gearbox would be in the "normal" upright position.

That just makes it all too hard. I just used a spring type fishing scale and hooked it over the bar and worked my along until the diff would start to move with 1 pound showing on the scale. If it moved at the 8" mark, then that was a preload of 8 inch pounds. (As an aside, the bolt head on top of the bar, in the middle of that stub axle is used for putting a torque wrench on when measuring the preload on an lsd, so it's a multi purpose tool .)
