Scarebird front disc swap-my experience

I did my 65 chrysler 300 with the scarebird set up.and bought all the brake parts locally,evering thing new,and did not worry about the cost that much,weather its 500-750$,I wanted to stopfast,straight and quick,and the scare bird system did it for me.So if you think its a good idea to try and stop with old used parts that might work,go for it,but when you need to stop a 4000lbs + car at over 100mph,and the used parts don,t work,think of the new parts,and how quick mine stops,mrmopartech
