Just wanted to follow up. Found an early Monte Carlo with discs, measured and duplicated the parts. (AutoZone, NAPA, etc.) fit just right inside the 14" AmRacing Wheels! If anyone wants a list of the parts used & part numbers, let me know & I'll post it. Fit great! Had to replace the master with one from a T-Bird (dual chambered) and add a proportioning valve (had one in the parts box) but worked great! thanks for all the suggestions!
