... I have had several sets of A body axles done by a shop in SO CA years ago, he made a mandrel that centered on the small axle register with the large 4.5 inch bolt pattern in it and then transferred the pattern to those axles, he would drill and tap them for 1/2 inch by 20 threads screw in studs Those worked good, lasted a long time, same thing on the brake drums, same pattern




Mine were done at the same place 20 years and 80K hard hard miles ago.

I paid Mazzolini for it. But really he just farmed it out to Sutton Engineering I found out years later. Mazzolini didn't do much directly in house. Just put together the right resources.
