Thie carpet that I'm looking for is for under the 3rd row seat. At the back of car by tailgate right by the well. The factory felt is there. My 79 Chevy Caprice Classic 4 door wagon must have been the cheap model. And didn't come with a 3rd row seat or carpet.
The 3rd row seat rear facing seat was an option on all 77-90 B Body wagons. Not having the 3rd row seat wouldn’t make yours a cheap model, there’s a lot of them out there without it. My 79 Custom Cruiser is a heavily optioned car. In fact, I think it has every available option EXCEPT the 3rd row seat. Anyways, the ones without 3rd row were given trunk felt, not carpet. So yours probably never had carpet there. To save my soul I couldn’t tell you how much carpet if any, came in the 3rd row floor on the cars that did get the seat. It may not be much more than a floor mat. Are you trying to deaden sound? Or you just want a pretty trunk floor? I’m a fan of both so there is no wrong answer lol For sound deadening any modern car audio shop will steer you in the right direction, it’ll prob cost more than carpet, but it’ll def help deaden road noise. If it’s for pretty trunk floor, I’ll go back to the auto upholstery shop recommendation. A good shop can cut, form, and sew auto carpet to fit exactly like (if not better than) factory. Again, look for the oldest people working at the shop. Not a slam on young people, they generally have more experience on all the newer types of upholstery. Heat forming, heavy pile, jute backed carpet for late 70’s GM battle wagons has been out of style for some time, that’s why I’m suggesting the old guys. Have you tried carpeting it yourself? With store bought carpet? Tape the back side of cuts, heat gun the corners, spray tack the verticals? May not look “pro” but I’ll bet it’ll look nice
And thanks, now you’ve got me thinking about pulling the felt out of my trunk and carpeting it. Lol as though there isn’t already too many things I want to do to mine. Lol
