If you don't have any at all, I can't help. If your old
ones are just worn past the limit, check with your local
automotive engine rebuilder. They send crankshafts and
such out to be 'spray metallized'. A process of building
up worn surfaces to factory size. They can restore life
to parts that are normally worn out. It's a little bit
expensive, but not horrible. I had engine parts, and brake
drums from an antique truck restoration done this way.
The actual shop that performed the metallizing was in
Easton Maryland but I have lost track of the name.
