Thank you A56. I had a 69 many years ago and it had the plastic side panels. Just learned recently that some came carpeted. This car did have the upgraded interior based on the fact it had door panels with the woodgrain and map pockets so thinking maybe for this car the sides are carpeted...but there must still be a structure for the carpet to mount to. As far as the subfloor, I never remember having that carpet out on my old one so not sure what is under that. Was hoping someone could post a pic of that cargo area without carpet installed just so I could see what it is I am looking for
