Even when using the hydraulic tob kit you still have to mount the clutch pedal, which is more than half the work anyway. All that is left after that is mounting the bellcrank. IMO these hydraulic throwout bearings open up a whole new source of possible problems, leaks, etc where the mechanical linkage is dead reliable and won't leave you stranded on the side of the road which is something to consider if you are really going to drive your car. I also don't like brake fluid that close to my clutch disc. I would use the hyd set up only in a car where there is no room for linkage but I haven't found that so far even with big block A-bodies with 2" TTI/chrysler power headers, ProParts/McCandless/Hensley? 2" headers, 2" tubular automotive or hookers. Might be a good setup for a 440, 4-spd colt?
