First off I’ll say I do not know exactly what they’re applicable for Now they’re all used, greasy with oil some with more scuffs and makes then the other some are seized pretty tight and everything will need to be gone over to get into working order They’re all marked with a number on the backside however there’s not any order to my knowledge as there’s multiple 13’s and 6’s and 7’s so use that knowledge however you can This is a cool vintage hot rodding piece but will need to be restored
