How to: Cargo light in a non cargo cab by LFD Inc. - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

[QUOTE=Longhorn Man;1729137]You mentioned mounting screws... don't forget you need the special rubber encapsulated nuts to prevent from grounding the light body. If you don't take steps to prevent the ground, your cargo light will stay on at 1/2 power or so.

There are two metal spacers I have seen for mounting between the inner and outer cab sheet metal? Is this correct?
Can someone chime in on these two spacers.
I am guessing they offer some stability for mounting?
Thanks,
Sam

Does anyone have a wiring diagram for the dome light?

I stumbled back on this thread . Here is a look at the cargo light added to a 67, I added 8-8mm red leds for the 3rd brake light function .

Now that looks awesome.
How did you connected it, to the break switch directly?

Cya,

Like Samkost, I'm wondering where the 2 metal sleeves go. Do they go
over the rubber nut "shaft", after pushing the rubber nut shafts through the holes from behind the outer sheet metal? Seems logical, but I ended up with metal sleeves with ID smaller than the diameter of the rubber nut shaft. I can drill out the metal sleeves, but first I would like to know if I'm on the right track.

Thanks.

The rubber compression nuts go in from the outside .just push them in the holes on the truck ,the spacers go over the mounting screws before being inserted into the rubber nuts . they provide support as you tighten the screws the rubber compression nuts expand behind the metal to hold it all in place yet remain isolated . this pic shows the mounting screw without the spacer in place . the spacers hold pressure on the rubber nuts while your screwing them in which helps the rubber compression nuts to expand behind the panel . Without them the rubber compression nuts won't tighten and just pull out of the holes . If you need more pics let me know .

The rubber/brass nuts are called "Well nuts" You can get them at the better hardware stores. I got some at my local Ace Hardware.... Fastenal has them too.
