69Mach1 M code 20 Report post Posted February 11, 2021 I am converting from an FMX auto to a 4-speed toploader in my 69. I've done some research on the linkage and release bearing but still am not sure which combination will work. I plan on using the Z-bar linkage but with a diaphragm style release bearing so I can switch from the original lever clutch to diaphragm design. Can I just switch to the diaphragm release bearing and clutch? Does the stock clutch fork work? Quote Share this post Link to post Share on other sites
