I've heard when swapping to 73 and up disk brakes your track width is increased 3/4" on each side. Are the Kelsey Hayes brakes at this increased track width or are they 3/4" each side narrower. The reason I ask is because I installed 73 up disks on my last 67' Barracuda and was running the 5.72 back space 17" Bullitt wheels with no problems. I'm looking for wheels for my new 69' Barracuda which has the Kelsey Hayes disks so I'm wonder if there's a difference between the two as far as track width.
