No idea on cost yet. He said that he can do a 6-speed as well, but he needs the tranny to do it. The tranny bellhousing is actually cut back the width of the adaptor and the adaptor is bolted to the bellhousing, and then the whole assembly is bolted to the block. Does the Z33 tranny use the same size/spline output shaft? Fortunately, the Z32 shaft has the same splines as the L28 tranny, so if you have a good clutch, it can remain the same.
