Hey guys! I'm in the process of tall spindle upgrade. My car was a non power 4wheel drum model. I have a 502 w/ headers & tall valve covers so, I was wanting a smaller booster for clearance. But, it has to have enough volume to support four wheel disc. Anyhow, enuff BS. The real question is the brake rod combo? I have a booster/master assy from like a 73 vette. 1st major prob is it's designed to bolt directly to firewall. I have a booster from a F body that I can use brkts off of to bolt vette booster to my firewall. The question is then how do I determime length of brake rod?? My car is 4 speed if that matters. That is all for now as I think I have most other things figured out. I also need a adjustable prop valve if anyone has one. Thanx, JOHN graemlins/beers.gif
