Lighter screw backs.
 

One of the details I have been attempting to finish on my C10 is the lighter.
The back retainer that was lost during the rebuild process. I knew it was around here. I came up with two and none fit. Well the other day I salvaged one from a truck and found out it was shorter than the others. I figured they were all the same. Well I have three different lengths and only the shortest is correct.
The short one is 1.5" long.
Possibly to make up for the aluminum bezels? Not really sure but I though I would pass this tidbit on.

I think the stock one is the Shorter.
Aftermarket Cigarette Lighters can be longer with a longer handle, unlike the stubby OEM one,
that looks more like a Choke Knob or Headlight Switch.

Maybe I can learn something here, where does a choke knob of headlight switch use one of these?

Re: Lighter screw backs.
 

What I meant was they are the same style: Black Plastic ~1'' diameter knob w/ steel center on Lights, Wipers, Choke, etc. Radio knobs and Cigar Lighter knobs also match.
Non-stock Lighter knobs have longer handles. The heat elements may be longer, too. Or shorter, IDK.:smoke:

Well I did just learn something...never put 2 and 2 together as far as the element length for a factory knob or after market clearance, makes perfect sense.
