I'm installing a set of 70 front disc brakes on a 69 mustang. I didn't realize that the proportioning valve was different between the 69 and 70, one mounts horizontally, the other vertically, also the ports are configured differently. I have the 70 valve and cannot locate a 69 valve, I need to finish up the work on this car. If I order a complete set of lines front and rear will this allow me to use the 70 valve with no other problems?
