Thanks, the brake booster was a custom setup. I just have to switch to an 8” booster from a 9Thats why its silicone, withstands heat better. We reused the original bottom fitting, simply cut the original crimp with a dremel to harvest the fitting and used the supplied hose clamps with new hose to affix. 5 mins.
We did play with the hose length a bit, and preload/twist to get maximum clearance for the return line from turbo and manifold but its quite quick and easy. Not sure how you have a master cyl clearance issue unless you have gone with some custom setup.
