I have a 60s model Corvette and spend time on Corvette Forums. LUX is represented as the OEM clutch manufacturer and is typically highly recommended including by the retired GM/Corvette engineers who participate there.

Because older Corvettes have limited clutch pedal travel, a specialist on there recently set up a rig to test the distance various manufacturer pressure plates have to be compressed at the fingers, to accomplish disc release. The results were rather surprising in that the measurements were all over the place which explained why so many 63 - 67 Corvette owners have problems with getting full release of the clutch and have transmission shifting issues. As it turned out a LUX clutch didn't test out so well - taking additional compression of the pressure plate to release fully - although it wasn't as long as some others. A McLeod clutch tested particularly well.

I just mention this because if you are going to increase the free play at top of pedal - be careful that you can still get full release and proper transmission shifting.
