There are two different chevy II bellhousings. #383 and #309. The #309 has a large trans input for the muncie and the #383 has a small input for a 3 speed trans. They will not work for a 168 tooth flywheel. I did the 4 speed conversion on the malibu. I had the g body bellhousing and 2 of the forks. They looked to rigged for me so I sold the 2 forks for $150.00 each and the bell housing for 75.00. Then I bought the lakewood. The lakewood works great. Just have to use the heavy duty truck ball stud. Just my 2 cents but think about how you may abuse the clutch set up. There isn't much between your foot and the clutch assembly on a stock bellhousing if the clutch decides to gernade.
