Front Disc Conversion

[Too Many Projects]

I have '69 single piston calipers and rotors on my '66 Chevelle. I altered the spindles per some instructions on Team Chevelle 12 years ago and don't recall what that entailed. They may have been from a '67 4 piston application to begin with and I only drilled out the bolt holes in my original steering arms...
I bought a correct appearing 1967 master and hold off valve/bracket from In-Line Tube and a correct 9" booster with the pre-bent lines. It all looks like it came that way from the factory. If you have all these parts from original cars, use them.
I purchased a kit from CPP first and gave most of it away, as it looked cheap and the CPP cast into the master wasn't going on my car. I think I used the backing plates and maybe the rotors...

Mitch is on a roll with good advise this morning!!

I too recommend using single piston calipers.
