small to big 8 3/4 bolt pattern

I tried a couple of machine shops locally. One would use a CNC's and quoted me $125 on for the axles and drums....until he saw what meat would be left over on the axles. Even using screw in studs he wouldn't touch it. Another place would do it, on manual machines and wanted around $400. I ended up ordering sbp steel wheels for around $300. Last night while looking on Summit, I came upon this for 8 3/4 rear ends. Disc brake conversion and lbp for $450. Wish I had seen this (or if they even had this) a couple of years ago.

Just looked at it again, I wonder if the axles need to be lbp, but it they are specifically for 65 to 72 A bodies
