Didn't save enough by building the shop/house outta straw so I STILL have to make stuff myself. With all respect to the nice parts HotRod Works makes I thought I could do well on my own using stock parts. This open drive conversion uses the rear of your stock torque tube, the stock coupler, a Yoke that fits your driveshaft (in my case a GM) and a seal that matches that yoke. This yoke was bored out on the lathe so the coupler would press fit into it(1st pic on the left, you can see the splines are gone, this is a FRONT yoke). The two were then welded together and allowed to slowly cool. At first I thought I would have to machine a "cap" that would neck down the size of the TT to the OD of the seal but I realized they were darn close already. So a piece of 3" DOM 1/8" wall was used. The tube was press fit into the TT stub, welded then faced and bored to be a press fit for the seal. All work was done with hand tools, sawzall and cutoff until the welding/machining parts. The total working time was around two hours tops. A few beers were sacrificed while planning how long,where to cut.etc.
