i know they are hard to find,solid and not rotted out.i have had no luck finding them,so if you have some and want to sell,i'll buy em!email or pm please.
maybe a . . . I dont have an immediate source on hand and usually when you see them they are all banged up and pushed in ( etc. ) , but, I do have an ideal ! How about fabricating some up, use a cardboard cut-out ( or similar template like your old ones ) and have, get, make, cut some out/up, drill some holes, test fit, paint up and go a new custom route. Or, just skin the whole insides with solid sheet ( like shaving the inner bed ) ! No more crud, leaves, debris to escape behind the panels. Ive seen grass and tree seedlings growing ina few toyota beds. And they say older vehicles cant give back to the environment ! L o w N l o u d
its looking like i'm gonna have to make some myself,lownloud.but i'll wait awhile and see if anyone reply's to this.i do have the old ones,well about 75% of them!it's funny too because the rest of the bed was totally rust free!
