Finally got my money together to do my build. Before I go buy parts I can't use have some transmission/clutch question. Going from 1977 400/th350/203 to 1980 sm465/205 keeping the 1977 400. When ordering parts it seems like factory 400's with sm465 had 26 spline input, my 350 sm465 has 10 spline input. So can I use a 10 spline 350 clutch on a 400 flywheel? Here's the flywheel http://www.summitracing.com/parts/RAM-1523/
