You can overhaul vintage pedals with removable dust caps if there is a problem in their function. Usually, the way to replace a pedal spindle is with one from the same manufacturer or model. If you have a bicycle co-op nearby, you can usually find inexpensive pedals. You can then fully overhaul them and shine them up. The Japanese made great pedals back in the day. I prefer two models from KKT, Pro Ace and Top Run.
