The re-pops are expensive but there is something to be said for new parts that are clean with no rust and bolt up like a glove and come with a new part warranty.
I put a re-pop set in a 70 road runner for a customer and they were very nice to every detail and matched what the originals would have been exact. They were well worth it. Especially if the car is nice, its not really that much money for what you get and its a one time shot to get the job done. Just sayin.
