I want to change the outer crank seals on my '74 RD350. What source for the seals do you recommend?

Thank you.

I usually hit the local Bearing and Seal Supply store and buy OTC. They typically have what's needed on the shelf, and most seals can be had under $10 for top name brands such as TIMKEN, Fel-Pro, SKF etc. If in doubt, bring the old seal(s) with and have them match them up.
