what do they go for? its just one i have acquired, i put the 6765 in my car i just have this one laying around need some $$ so thinking i might want to sell it but want it perfect for buyer...or may keep it not sure.. im going to soak it in penetrating oil for a bit and try at it then... maybe i'll just send this one to you bison how much would you charge me to freshen it up to sell it in perfect working condition.
