so your brake boosters got clearance issues

[grumpyvette]

its not at all uncommon for the stock brake booster or master cylinder to cause a clearance
issue on some swaps so heres a few ways to avoid or correct that problem.

hydra-boost is basically a hydraulic assist using the power steering pump pressure to
help the brakes rather than engine vacuum, allowing you to gain about 3"- 4" more valve
cover to vacuum brake booster clearance, in many applications,

some times you need to mount the master cylinder along the frame under the floor to get
the required clearances, now obviously this requires different linkage geometry but its not
beyond the ability of anyone willing to research and fabricate parts.
