We have recently found out that the original clutch master cylinder listed in the plans (5/8" Wilwood) does not have sufficient volume to cycle the slave cylinder on the trans all the way. This causes the clutch not to disengage all the way. Originally it was thought to be the size of the line, but 3/16" line is fine.
The new master cylinder is Wilwood PN 260-3374 (3/4")
