I've done this
I had the FORD ends welded on my 10 bolt. The axle lengh is determined by how wide you want the rearend. I kept mine the stock width. I told MOSER that and they supplied the correct 33 spline axles. I also used a FORD drum brake kit that bolted directly to the rearend. The brake line tubing only had to be hand bent a couple of degrees to bolt to the FORD brake cylinder. BTW, the FORD brake shoes are a helluva lot bigger than the GM set-up. In the past I used 2 sets of shoes so I could use the 2 longer ones to get more surface area contact patch. Before I installed the t-brake, with the FORD brakes, I could hold 20 plus lbs with no problem, it was like being tied to a tree. If I remember right, the drum kit was like 65$ a side and that included everything already assembled, backing plates, drums, cylinders and shoes. I've got almost 1,000$ in the hole set-up, brakes, 33 spline axles, 33 spline spool, FORD ends, all new bearings and the labor to have the welding done.........if you go this route, be sure to use a welder that has the correct jig to set the rearend up with.......good luck
