As a suggestion, maybe have a car registry. I know I'm sitting on parts and knowledge useful to other Hambers, and I'm sure others are also. If we had a registry ie: 1955 Chevrolet or 55-57 Chevy where we link in by year and make. Anyone looking for parts or knowledge would ping membership with that particular type car. I'm too lazy to list parts laying around, but if I was pinged by someone looking for what I may have thru the registry, I may be able to help. This make sense?
Might be a tough road. Hard enough getting guys to print where they live in their profile or read the rules for posting. There are car specific social groups but a lot of those are ghost towns.
That was what I was going to suggest - there may be a social group dedicated to the tri-five Chevy's already and you should check there. If there isn't a group, you could get one started up.
