I have a 1974 Camaro/Z28 with a manual 4speed trans, I was told the trans is a Munchie Rock Crusher is there a way for me to tell what size clutch and spline count is in this trans,I can get a deal on a Hays clutch set just for a spare with is a 10.5 and 10 spline and will this work if mines is a 11 inch and bigger spline?THANKS
