kelsey hayes part and proportioning valve
not sure what your saying?
Just look at the pics and you can see the differences.
I had to massage my pre-fabbed lines slightly to make it work. It was simple. Little bends here and there.
I don’t see why you can’t make the heat shield fit. Nothing about the newer style valve obstructs the shield, it’s easy enough to adjust the lines imo. It just slightly longer on the bottom.
I dig the shield. Pain in the *** I bet to move if you are looking for brake line leaks.
If you want easy plug and play. Get a pre-made set for a 1970 a-body. Your choice of mild steel or stainless. The stainless requires a bit more torque to seal properly.
