Thanks! Just curious how you actually convert a regular clutch to an adjustable clutch? Do you have to change the springs and add adjusters (bolts that preload the springs when turned)?
Yes, you need a different spring, the adjuster and levers with an outboard hole (some levers have an inboard hole as well) and then you can adjust for plate load and counter weight.
The difference between and Borg & Beck cover and a Long cover is that the Long cover is taller. Therefore you can use longer springs and have a much wider adjustment range than you can get with a B&B cover.
For example, and Long cover can go from 300 pounds to about 1800 or even a bit more.
The B&B cover I run is from ~400 to 995 pounds. And I run a Long lever in the B&B cover.
