What is a rust free rear valance with dual exhaust cutouts for tips for a 72 Road Runner/GTX worth?

Can't find pics currently but its clean.

$100 to $200 just guessing. Any nice valance, front or rear, for any old Mopar car is typically $100 to start.

Wait, what? Maybe I'm a lot removed from this part of the hobby, but a 71/72 b body rear valance with dual cut outs for $200? WHAT? Someone in the know with current sales please chime in.

I'm seeing brand new ones on eBay for $300-ish, but they say they fit 1971 B-bodies. Something different, or special, about the 1972 part?

71 and 72 Plymouth B-body rear valances are different. 71s are straight across the top while the 72s are shaped to match the rear bumper.

71s are reproduced by AMD. 72s were not.

A 72 with dual exhaust cutouts, in rust/damage-free condition, is easily $500.

when i re did my 72 RR 30 years ago. i couldn't find a remotely decent dual exhaust rear valance for less than $200. i ended up buying a standard valance and welding the exhaust cut out area to it.

IMOP if it's in fair to good condition i can easily see it selling for $500. problem is finding someone to buy it. shipping this part will kill the value. i can easily see $150+shipping charges. and it will probably get severely bent from shipping unless packing is done very well with something solid like a board to keep it from getting bent. or double boxing it.
