I had the pipes custom bent, but we used an original for a pattern, so they are stock other than the pipe diameter. I am going to try putting a zip-tie around the boot to cinch it up some on the lower end next to the pipe and see if that give me enough clearance. I will try that tomorrow night and let everyone know what the results were. I will also try and get some pics of it.
It is really close even with the factory pipes--that is why the originals are always really hard from the heat.
I also have a centerforce clutch in my car, which may cause the released position of the Z-bar to be a little further down than a stock pressure plate would be.
Anyway, I was very pleased with the boot and it fits the Zbar well ! Also was very pleased with the other parts I got from you Doug!
