I finally laid the carpet in my grandson's 56 F100 to see what problems I might encounter. The master cylinder fill hole, battery and because I used the 53-55 gas tank all must be accessed somehow by either cutting out the carpet or somehow being able to remove the carpet for access. Any ideas are welcome.
Is it best to just lay it down or do some sort of stretch on it like house carpeting?
I would think if it was just laid down it would stretch the fabric over time and leave wrinkles. Just like my 65 merc has in it...
Look at Rich56"s carpet and see how nice and tight it is. I took the advise of using 2" wide velcro glued to both sides after stretching and it seems to hold just fine. But before doing that, I installed all-thread in all the mounting holes. In most of the holes in the floor, I installed gripserts, but you can install a short bolt from the bottom and lock it down with a nut to achieve the same result. I then drilled some different sized round stock on my lathe to press over the studs. I then heat the round stock with a propane torch and push it over the studs and walla, you have cauterized holes. You can also use a single edge razor blade and cut an x on the stud and achieve the same results. Hope this helps someone.
I found this place that primarily does boats. Looks like you can do custom orders (sounds expensive) but better you can just buy the snaps and tool to install them your self. Custom Marine Carpet
I am ways away from interior but sounds like a decent ideas so far.
