I have been restoring pedal sets for several years. I keep finished parts on hand and can usually build most any year set from part I have for a quick turn around. I can also rebuilt your set. Here is a picture of one I recently restored. I zinc plate most of the pars including the housing. The pedals and housing are then powder coated. Bronze bushings and new springs are used. I can alos modify the clutch arm to use a ball bearing to replace the bushing which is prone to excess wear.
Cost is $300 plus shipping for most sets. 1975-1985 sets are $350 and G50 sets are $400.
In some cases I can sell a set outright if I have a good supply of core sets.
Thanks for looking.
