14" wheels for disc conversion okay?

I want to go with chrome Rallaye wheels, larger bolt pattern, but 14". My concern is so many disc converson seem to be for 15" and larger only. SSBC has the smaller ones. I am going to try and drop the K frame (no drive train in car) and the Schumacher mounts, change all the suspension parts, change torsion bars, and swap to disc brakes in the drivewy garage. I have no idea what I'm doing or getting into either. Should be fun with a lot of yelling.
Rockerdude, I'd like to have every car you sold. Great cars all of them.
