Fun job. I just did mine. Plan on lots of interior disassembly before starting and a good vacuum cleaning. Hopefully your old carper comes up as easily as mine.
I installed mainly using contact cement (I needed 1.2 quarts) from any hardware store and several throw away brushes (I went through 3-4 of them). For the more tricky bits such as sharp bend and limited support areas, I used fast drying weatherstrip adhesive (any auto store); I needed 2 tubes. I also kept a supply of single edge razor blades handy.
Once you determine the order of installation (important) ... lay a carpet piece in place and determine if any cuts are needed (back panel and fron front side panels that wrap around complex corners). I would often use a marker to outline the glue area when it wasn't obvious.
Then I applied glue to the car surface (abiding my marks) and carefully placed the carpet down and rubbed - the idea being for the carpet to pick up a glue outline. I then pulled the carpet back up and gave it a coat of glue where it made contact. With both pieces glued I would put them back together, rub, wait about 2 minutes and pull them apart. This activates the contact adhesive. After another few minutes you stick them together, position carefully, and rub into place. You should plan to rub each piece down a few times over the next half hour as you are doing new pieces. In areas where I wanted to ensure an extra good bond I would apply weatherstrip adhesive from a tub (both surfaces) instead (some corners and edges)
The first piece I installed was the back panel with the vinyl top edge. I used weatherstrip adhesive and set the top vinyl first using lots of spring clamps and binder clips. I then cut an undersized notch for the drive shaft area and then carefully slit the channel in a few places with a razor so that it laid down nicely.
The pieces I did last were the trim bits around the seat; the small goofy peices and the pieces shaped like an apple with a notch out ot it (this had to be clamped).
I chose to do mine on a cold day. This made it necessary to bring a small space heater into the car with me. Other than AvGas and Napalm, few things are better in a small area with a heater than contact cement. At least it was better than being in the house with my wife and daughter. :twisted:
I've provided a simple drawing showing the relative placement of the pieces - hopefully you can read my bad penmanship!. I've also numbered the pieces in to a general order of installation (from my recent experience) and noted cut areas and area I recommend weatherstrip adhesive.
I think I drew the pieced by the door (by seat) inverted? :?:
