Mine didn’t cost me anything but a BIG pile of 70-72 Swinger parts. The guy that I traded my Swinger parts to paid $4000 plus another 1200 for a Glen Ray 065 radiator made from NOS tanks. Which i’m scared to put into the car, so I bought a used 065 to put into my car. The Glen Ray sits in my shed in its shipping box.
I paid a grand for a used one, got the shroud for $50. Then there’s the special throttle-kick down bracket. These cars get passed around till it comes to pay for the BIG ticket items.
