WTB 74 Charger rear pan (foot well)?

[anderson74]

Hi all-

I'm looking for the rear floorpan (footwell) sections for a 74 Charger. I've found some cracking where the rear rails come into these sections

Any leads here? The only new replacement sections I've found are from "Body Shop Price": 1971-1974 Dodge & Plymouth B-Body Rear Floor Pan Set (Sold As A Pair)
Any experience with this vendor? Also, the listing states "Originally patterned from the 1971-72 b-body it will fit all 1971-74 models listed below". I vaguely remember reading somewhere that minor modifications are needed to fit 73/74...can anyone speak more to this?

(already DM'd moparmark, no luck)

Thanks in advance for any leads or info!
Andrew
