Where do these screws go? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have 2 extra parking lens screws in my fairly well organized baby food jars from when I took my 72 truck apart, but I had 10 of the screws in the jar marked "P.Light Lens".

I only took one truck apart...do these get used somewhere else?

My daughter was the baby eating babyfood at the time and now here daughter is past babyfood...tells you how long ago I started this project!

Maybe they were loose in the ashtray...my best guess.

Them are lens screws

Front directional lights, tail lights, backup lights, cargo light all take similar screws some are different lengths though.

The rear lenses take a straight threaded machine screw whereas the front parking/driving lights have these shoulder'd machine screws.

Cargo lights use something similar, but they are much shorter.

I believe all the lens screws including the tail lights use a shoulder screw so you do not over tighten them and break the lens.

I will double check my parts stash.

These are tail & reverse lens screws. Perhaps some had a shaft like the park lens, but to-date I've never seen them.

All of the old rear lens that I have acquired (two sets) have the straight machine screws that 71Chevyshortbed402 posted.

So, I have 2 extra shouldered screws that are used in the parking lens unless they are used somewhere else...small mystery.

they come from the same truck? I suppose the housing on an elect. component could have used those screws, but that seems a stretch - I only know they're for park lens.

Those look a lot like the screws for cab lights. But then you'd have 5, not 2.
