Just bought a convertible chrysler lebaron

Very familiar with them. Had a couple myself back in the day.
What size engine? If its a 2.2 the wrist pins will rattle, but its just the nature of the beast. Keep the carb cleaned out. other than that, those things are tanks, can't kill 'em.
oh yeah, the top will leak, but will keep you mostly dry. More annoying than anything.
