Title: 68 Shelby rear panel screws
Post by: shelbydoug on October 11, 2023, 08:48:49 AM
Are the black screws that hold the rear fiberglass taillight panel in place "black stainless"? Are they truss head or something else?

Wo! Mine were black, like the current black stainless. they were put away in a safe place but no one remembers where that safe place is? Too safe.

I remember the heads. Philips pan head or truss heads. Leave it for me to have something not of the ordinary. Maybe I found them and they weren't as remembered? Ah. Misery.

If you are referring to the tail light panel.. the screws used were a self drilling phillips screw with a molded washer head.

Black oxide and silver zinc were used throughout production.

Thank you. To your knowledge is the black v. silver random or specific to build date groups?

My black ones had a sheen to them unlike the flat black on chassis parts and bolts and no apparent corrosion. That's why I thought they might be black stainless?

Couple of unrestored examples to illustrate finish and shape of the screw heads. Zinc ones are pretty shinny but not sure how often they have been rubbed and cleaned over the years. Seen allot more of the dark ones

There are 2 ? fiberglass or fiberboard pieces (one on each side) that cover the taillight/brake/turn signal bulb housings INSIDE the trunk. One abuts the spare tire. The repros I got from Parts Depot are black, but the one i have remaining on my KR is grey. Which is correct? thanx steve

Well sort of both, with explanation  They were black then painted/coated on the interior side with gray paint.

An original example that I hope will help. Choose this one to show the coated side and the base material

I thought " https://www.deadnutson.com/ " sold the gray panels but none show on his website anymore. You might call to be sure because it would certainly be the best alternative IMO. If he doesn't you will have to modify the black ones to make them look more authentic. . The repro material is not near the same as the original which was water resistant and had a smooth non porous surface unlike the rougher black paper that has a somewhat furry to the touch surface. You need to seal it with some coats of grey filler primer and do sanding between coats so that if is smooth when you lay down the final finish of grey so that your new pair match's the one panel that still exists in your trunk. After the final coat I use a semi gloss clear to complete the process to mimic the finish on the originals. I hope this helps.

I got a pair from DNO but they have a "reverse" bend I have not gotten out yet. I haven't tried. Thanks for the tip as I have 1 original panel from my car and I'll try and duplicate the finish on it.

My panels were always black. I thought that the grey paint was only a 69-70 thing?

Thanks for bringing up the bend. The boards should be pre bent and not bent to fit when installing in the car. There were typically no creases in the factory panels . The crease will most likely happen if you try and install without pre bending. I find something with a large rounded surface and carefully persuade the cardboard back and forth to bend without putting a crease in the board . Once the board has that bend memory it will be easier to install with out putting a crease in the card board.

Bob, Would heating the piece with a heat gun help with the bend as well? thanx steve

Mine came from Jack with the bend backwards. I wish I would have bought the vert trunk divider as a spare when he had them. I'm told probably gone forever.

Heating them probably wont work

They dont need to bend much, using a round concrete form, to slide the cardboard into and gently applying even pressure, leave overnight and they are formed

Thank you. I got one of my originals for the shape. So DNO pieces are for 69 and 70 so what is different about 68s? Anything?
Title: Re: 68 Shelby rear panel screws

The shape is different between the 1968 and 1969 models. 1969s generally have screw holes as well

Two basic questions here:
1) etching or non-etching primer?
B) Is the rearmost surface, the one you don't see, black or blue-gray?

Black on inside blue/gray on side you see

Primer gray is close, but its actually closer to a Volkswagen color from the 1960s. Sorry I dont have a code or color name.

Its going to soak into the cardboard, so you will need several coats

So, primer gray when all done, or blue gray as your website suggests?  Sorry for the redundancy. s

I think the color of the ones Jack sells is pretty close if not spot on(have yet to do a side by side comparison). I have an original one put away from my car and I was thinking of getting the paint color matched at painter's supply next summer. I've done that with PS pumps and 69-70 Shelby grill/bucket color.
