Hunt for 4-Speed Parts...

I think the price is reasonable for all that's included. That linkage stuff will add up in a hurry if you have to buy those pieces one-by-one.

When you get a set of pedals, take the pivot point apart and make sure the roller bearings inside are in decent shape. Some pedals used roller bearings, some used a bushing. I think the '69 and older may be the bearing style... ?
