I've been offline for a few days helping with my son's Eagle project. Thanks for the info.
ACC is willing to take back the carpet they sent me - it is trimmed a bit too close for comfort for what I can tell, especially the width. it appears to be pretty much the same width untrimmed as what came out of the car, and that was a little short from shrinkage or compression of the padding at the rocker panel on one side. Too close for comfort but they are accepting it back.
In the meantime I've found Newark Auto:
http://newark-auto.com/replacement-carpets/They manufacture sewn carpet kits, not molded, so it definitely has a different look and will look a bit different from stock, but I've seen nice sewn carpet installations before at car shows on other models and that would be acceptable to me if its well executed. The price is about the same but they are swamped with orders so it will be well into the summer before they ship. They said they use a different pattern for the 1975 versus other years so that's a good sign. They also sell reproduction floor mats.
I'm ordering spare carpet for the rear seat back and a new cargo area mat, there may be enough left over to cover under the rear quarter windows and the underside of the hatch as well, but they are unsure how much extra yardage will fit in their standard shipping box.
I'll still have to have the local upholstery shop sew binding around the new seat back carpet in place, and hem around the new cargo area mat. I'm not sure if I want to have a faux spare tire cover sewn up or just extend the mat over that area with a cover of some type. Either way it will be a hidden storage area with a cover. I'm not going to put new rubber on the compact spare so there is no point in lugging it around - I have AAA premier if I have a flat.
I'm not sure if the carpet has been messed with before, but the passenger side had significantly more padding with a white cotton batting as the bottom layer, but the drivers side didn't have that. Seems odd to me. the padding was all pretty musty so it will all come out, I'll figure out how much replacement padding to install once I see how the new kit fits. For now I'll take everything down to metal and give it a nice rust preventative treatment before building back up again.
If anyone needs any reference photos of the floor, or while my instrument cluster is removed now is a great time for special requests.
Thanks again for the info. I would love to see any photos of the work in progress and the finished product Clyde.
