I'm mating up an 8ba flathead to a T5 using a 50 shoebox bellhousing and wilco adapter. I'm having problems with the clutch fork staying engaged in the throw out bearing. Is the only thing that holds the fork inplace is the flat springs that wrap around the two bosses on the fork? It's also got that tiny spring behind the fork holding it in place, but it's always coming out. It's there a particular way to install this?
