I pulled the seats and carpet off my 67 yesterday. I am going to order the new replacement carpet but wanted to get some suggestions on this project. I noticed that they have under carpet liner and also sound+heat insulation available at the place. What do you guys recommend, the car is a little loud and it would be good to keep some of that noise outside. I have not purchased anything yet so all suggestions are welcome.

Thanks

I used the stock asphalt sound deadener and 1/2" mat type insulation from work.

Lots of guys have used Dynamat or Fatmat with favorable results.

Put in the best you can buy and as much as you can, also install it going from drivers side to passenger side not front to rear. Use a small wood burner or soldering iron to make the holes for the seats and seatbelts it makes for a much neater job. :cool:

Another question, the guy who is doing my seats said I had to glue the lining material and then glue the entire carpet to the liner or I would get carpet bumps and/or the carpet would move a lot. I dont know if this is entirely true while i am aware that in the first weeks or so it may not look 100% perfect the carpet will eventually settle into the floorboard. Im thinking to use glue only along the perimeter and some other key areas does this sound about right?

My matte (jute padding) is glued to the carpet, but not to the floor. It doesn't move around at all. I can't imagine the mess trying to scrape all that off when it came time to replace the carpet again.

JC Whitney sells some pretty good heat and sound insulation, it's about a half inch think, and foil on 1 side. I used it under and behind the backseat, and when I next replace the carpet, I'll use i under there, too.

Dynamat is way too expensive to line a whole car in, unless you print money for a living. I did put a sheet in each door, and line where the speakers went with it, works good.

I simply use more jute for insulation...inexpensive ($10?), light-weight, doesn't mildew, great sound deadener, great insulator, and easy to cut and fit. Pick up a couple of yards at your local interior and/or top shop. There, I just saved you $150.

I don't glue anything to the floors and never had problems with the carpet walking or wrinkling. The rocker sills, shifter plate, toe-baord, and kick panels, seats, seat belts, etc, all keeps the carpet in place.

As far as holes for the seat bolts and seat belt bolts, do this,..partially screw these bolts in first. Position the carpet where you want over the bolts and cut diagonal slits (don't cut with the carpet grain) over the bolt heads,..just enough to allow the bolts to come through the carpet. Do not cut holes,..this always looks craapy...cut 3/4 inch slits,..that's what the General did.

The rest is straight forward. Use a box-cutter with a new blade.

Good luck!

The feet for the seats were not installed over the carpet by the factory. On the fronts, the front carpet piece abutts the legs of the seats. For the rear feet, a flap was formed by cutting 3 sides of the rectangular footprint. ("hinge" to the rear) After the seats were bolted down, the flap was folded back over the seat feet.
