1966 Barracuda disc brake swap

drum LCA's can be used if you drill out the 2 bolt holes to disk specs, IIRC they are 1/2 on drums and 9/16 on disk. I had brand new LCAs n my 10" drum brakes and when I got the disk stuff i asked myself why I couldnt use the drum LCAs and the only thing I noticed was the holes were larger on the crappy disk LCAs I got off the donor.
