OK, here's the deal. I scored a set of Scout axles (30/44) with an aftermarket disc brake conversion (SteelTech Solutions, now out of business). I was thinking of swapping axles, but ended up deciding to move the disc setup to my '73 30/44 axles. Front is fine, swapping everything from spindles out. Rear...um, not so fine. One slight problem to figure out.... On my stock '73 D44, the flange on the end of the axle tube is 6-bolt 3/8"). The flange on the Scout axle is 4-bolt (1/2"). I am flipping back and forth between redrilling the axle flange for the 4 bolt retainer (1 hole almost lines up, 1 hole barely lines up, 2 holes would be in between other existing holes), or drilling the brake caliper bracket for the 6-bolt. If I drilled out my axle for the 4-bolt pattern, I'd have to pull the bearings off the axle shaft on both sets of axles, to get the flange retainer off, so I could swap the 4 bolt retainer plate to my axle shaft. If I stuck with the 6 bolt pattern, and redrilled the disc brake brackets, I'd have to make 2 spacers to make up for the missing backing plate. (I already have these from the 4-bolt Scout axle. The bracket would catch 3 or 4 of the 3/8" bolts, depending on clocking. Ideas, opinions?
