I'm looking to do some research on pontiac disk brake conversions. I'm interested in the LS1, C5/C6 conversions and have read a TON of threads and info regarding the chevy GM 10/12 bolt swaps but have found nothing for the original 10 bolt in my 1970 pontiac GTO. If anyone could share a link to a thread I'd appreciate it.
I started doing this research after reading this statement from Tobin of KORE3..but couldn't find much else:
"it makes a difference if you're working with a BOP 10/12-bolt with positively retained axles versus a 10/12-bolt with c-clips. The center hole on the LS1 backing plates is 72mm [2.835"] and the BOP axle bearing has only a 2.75" outside diameter. What this means is that you'll need to machine a spacer to go between your original retainer (assuming it can move outward on the axle far enough) or machine your own retainer. Anything that isn't an open "C" profile or two pieces will require the removal of the axle bearings for installation."
