I have for a 1970 Challenger:
2 grills, I pulled these off of cars back in the early 80's. They have been in my garage attic ever since. $450 each plus shipping.
1 pair of Mopar Performance Stage V heads from my 505 horse 500 crate motor (1998). You literally cannot find these heads anymore, they are that rare. $800 for the pair.
1 pair of mopar axles for the Challenger 8 3/4 rear end. I took these off a junked Challenger in 1977. $200 for the pair.
1 AC / Heater box for under the dash for the Challenger. Same car as the axles came off of. I have never taken it apart. For a true AC equipped car, $750.
Lastly for a 1970 B Body - one pair of new Mopar Performance rear springs, powder coated, never put on the car. $300.
These are all in Miami, South Florida. If you are somewhere nearby, I can meet you halfway. Otherwise, everything here will have shipping costs added to these prices. If interested, email me and I will send pictures of whatever you are interested in.
