Automatic Kings in Riverside, Ca. on Rivera street sells them for $16. And they do ship. But you might have to order that rear seal separately. I get those at O'reilley's.

I'm looking for this rear seal I buy a complete set specific for a 65 904 some reason that did not have this seal. And some of the things I thought it should have.

I know a high school teacher her students can only tell time with digital clock. They only know 9:40 if you say 20 till 10 they don't know what you mean
