Thank-you everyone.
Marley, I didn't know about Bike Tools etc! Wow! Excellent.
CMC, thanks for the offer. If I can't find one in a reasonable amount of time I may take you up but it looks like there are good options. I worked at Chula Vista Schwinn back in the 70s. Haven't had the chance to ride in San Diego in a long time. Great riding there.
