LBP brakes on an Early A

Sure, get a disc/drim mc too and proportioning valve or combo valve off disc/drum vehicle.

Fyi spindles were different for disc obviously, and the uppers have a larger ball joint. Lower control arms: you may find your drum lower ball joints have a 1/2 bolt hole while the disc have a 9/16 hole. You can drill out, no other difference. Did mine like that, no problem but i had 10's.
