Did ford racing ever make an orange RR? ASAP!!

I would inspect them all very carefully though. Make sure all the needle bearings are free spinning and that there are no cracks on the body or flat spots on the tips (or any signs of visible wear for that matter) on them. Even thought they do sound like Harland Sharp rockers (which as far as quality is concerned are one of the better brands) if this guy tried to pull one over on you with regards to who made them just to make the sale, he might also be the type of guy who would knowingly sell a broken or defective part to make a sale as well.
