Hello , I originally reached out for more info on installing a Powertune brake booster ( servo ) on my BJ8 and would like to help the next person and give a bit of feedback on my installation experience . I have work on British cars for 50 years and did find it a bit of a pain . The Powertune un it is built to fit a various cars with the same booster. The instruction were not helpful and needed to be instructions created for individual cars . I purchased the extra bracket for a Healey , which worked but I had to redrill the mounting holes , once I figured how the booster was mounded . There is little clearance when mounted and will have to remove booster if I were to have starter problems. Other issue I had was with the brake pipe supplied in the kit ,the threads were to short and not allowing pipe to seat against flare. Once all sorted out it does preform well , next time I may look into a different brand servo, try to rebuild mine or not use one . Happy Healeying , Jeff
