Ground Effects Plastic Type?

[Turbobill80]

I found my original front fender ground effects, but they have broken tabs. The service manual just calls them thermoplastic. Does anyone know what kind of plastic is used. The unpainted area is yellowish. Thanks for any help.

Thanks for the info. I have 2 new ones, but I like the old ones better. My left one is only missing 1 tab. The other one has a crack and is missing several tabs. There is damage to tabs on the bumper and to other plastic pieces too. The reproductions seem heavier and made from a different material. Also, I want to learn how to weld plastic. Knowing the plastic type I can order some rods and pick up some junk parts to practice on.

I do see Frank had some and they sold. I had called previously and they didn't have any. I bought a couple of new ones from Classic Industries.

Polyurethane Bumper Repair

Thanks, for the link. I was aware that the welding rod acts like a structural hot glue, since the underlying polyurethane will not melt. I did use some JB Weld to rebuild a shattered outside mirror base on my Tacoma.
