Axles and re-drilled rear drums for 4.5 bolt pattern

FWIW, I recall having issues with screw in studs on the re-drilled stock flanges. Loctite only lasted a short time. If they weren't tack welded they'd back out on ya' when swapping wheels. Was using 1/2 X 20 X 2" RH Gr 8 cap screws with ground heads.

My "re-drilled" Mosers have a thicker flange and use press in studs.
Thanks, I'm hoping that they have an explanation because they specifically asked quite a few application questions initially and I mentioned why I went this particular route. There was no mention from them about any type of potential interference with the parking brake strut. So, I'll just wait for their reply.
