Why can't we just go back to the designs from when cars were unique and didn't all look the same?

Very weird set-up.

Never time to do it right, always time to do it over.

If your bell housing doesn't have the built in pad for the slave cylinder(for V-8/mechanical clutch linkage),it's easy to make one from a little piece of angle bolted to the two upright inspection cover bolts behind the oil filter;drill and thread two holes in it to match the slave cylinder holes. The clutch fork from either V-8 or six set up will work fine. It'll be plenty strong;mine lasted through 3 engines. The hose will be too long;you can either route it to use up the extra length or replace it with a shorter one. I just ran mine up the firewall and back down to the slave cylinder with a loop in it,because it worked fine and I didn't wanna have to open the system and have to re-bleed it,and because I'm too cheap to buy another line.
