How can they be retrofitted? I restored this truck many, many years ago and now, since I'm wanting to sell it, need to install the 3 trim strips per window. I have the D nuts but can't get behind the door panel to install them. Theres also footman loops on the doors for a check strap that utilize the inaccessable D Nuts. Has anyone else successfully done this?

No, Steve. They'd simply lift out of the D hole in the panel when screwing in the countersunk oval and slot headed machine screw. . . . wouldn't they? A few remnants of D nuts are in the door panels and it appears the 'ledge' around the nut is on the inside of the panel and I thought that was to keep the nut from lifting out. How are the nuts fastened to the door panel that connect your footman loops?

I believe they were originally set with a press, but you could probably clinch them with a hammer if you have a good heavy anvil to back them up. I'm thinking the flange around the countersunk hole gets rolled over the edge of the sheet metal. Of course, you might also tack weld them in place.

They are set just like a rivet but with a special hammer face die. I've tack welded a few that I couldn't get a bucking bar behind then just ground the face nearly flush. Use whatever method you can to insert them from the inside and hold. I've used everything from a magnet, glued to wire or popsicle sticks. I hold them in place with a screw and C-shaped bridge until they're tack welded on two sides.

By the way George, did you get my email on the lamps?

I think you could replace them with a rivnut installed from the outside.

Thats just it Ken; I can't insert the D nuts from the backside of the door panel. Theres no way of entry. The flange around the D nut, seems to me, should be on the inside of the door panel so the machine screw can fasten the trim down tight. Gonna go and research what a rivnut is Ted. Good to hear from you. Are you repairing the touring yet? Now I'll check my email Ken. . .

A rivet nut might work but you'd have to fill the hole and re-drill it. The flanges on rivet nuts aren't large enough to fill a D-hole.

Oh well; if I sell the truck, I'll just give the trim strips to the new buyer. . .
