I just talked to a brake and clutch place near by to see if they would have a return spring and he didn't but he told me that he has heard of guys having problems with adding residual valves with these none adjustable proportioning valves because those valves have built in residual valves. Anyone heard of that?
Oh I also found these springs http://www.brucesspeed.com/kingmaste...springkit.aspx and speedway has them as well on sale for 14.99. The only thing is I would have to remove the rubber dust cover to install it.
