Preferrably. 6 stud.

I'm quite happy to use an adjustable proportioning valve. Had to implement one on my '70 C10 having done a similar assisted disc brake upgrade on it.

Understood. I would prefer to have vacuum assisted brakes.

Did not know this. Dual system is a must. Braking is not to be compromised on.

Given the above, what would the recommendation be? Perhaps this ? : https://www.classicperform.com/Store...s/5559CBK6.htm

Could I use the hardware from a 73 onwards with a bracket?
