carpet trim

On 66 and older cars there are actually 2 different plates in the door area, the carpet hold down and the sill plate. I've seen the carpet hold downs in one piece that go all the way back to the wheel well between the rear seat and the qtr. panel, and some i've seen have a small extension piece that finishes it back to the wheel well.

I have a bunch of used ones in decent shape if you just need some, but I do believe Keith is right, Laysons has both the sill plates and carpet hold downs in reproduction form!! Geof
