Hydraulic clutch or stock linkage?
if brewers hs 10.5 that is the later stuff,your 66 originaqlly came with a 9 inch clutch with a v8,,,if you go with linkage,im dont know if brewers has the frame ball stud mount or if he has adapted something,, i have a frame ball stud mount for that car,,,it is original to 1963 64 65 66 A body only,,,its for sale,,
the advantage to a hyd set up is clearance around headers it much better,,,if you dont get the correct linkage parts it will bind,,,if you run a big clutch heavy presssure plate with linkage,,,you will need a big foot to push the pedal and you will have to makea a fire wall brace,,,hyd is much easier on your legs,,
