Need help finding cab clearance lights

My father is accidentally doing a full restoration of a '69 C20 pickup. It has some weird but factory cab lights, but one of them has been replaced and doesn't match. He wants to get a full set but can't find this 2 year only hockey puck style. Everything is the fireman's hat or teardrop style.

Anyone know where I could find a set of these?

I can't find anything like that on Truck-Lite, Peterson or Optronics catalogs. Does the newer one have any markings on the lens?

Grote has a pretty good selection of round clearance lights. I'm guessing most are meant for trailers, not cabs, but I don't know if it really makes a difference. You might have to get creative with the gasket to seal it.

Make silicone mold and make a new full set?

My buddies '73 had the teardrops. For some reason I'm a big fan of these lights.   

Are your dads stock Chevrolet?

Wow, even LMC Truck doesn't have them!  With the circular boss on the roof, anything non-OEM won't work.  =~ (

Correction: 

I googled 69 chevy clearance lights and LMC Truck popped up; the image shows exactly what you need but the text doesn't match.  I would give them a call.  1-800-562-8782.

You are probably going to have to go to a commercial truck supply place and find something the same diameter. Maybe these guys. https://www.vehiclesafetysupply.com/index.php I had to do the same thing to find lights for SanFord.

If there is any information on the existing lights a google search may turn up something as well.

Weird, my '70 c50 has the fireman hats I think. Which reminds me, I need to replace a broken one.

Nothing to add except that I have never seen round ones like that. 

They were mid year 69 to 70 only.

Porsche 911 R lights ?

there are generic lights that look the same from China etc

2 1/2 - 3 inches across ?

Looks like these have the round base with two screws and grommet but different shape for the light.

I don't know why the picture is weird.

In reply to Shadeux :

It's been a year, I assume he found something. 

In reply to Steve_Jones :

Thank you. I always assume it's fresh.  

I haven't found a set yet but I'll be dammed if I'm going to send $200 to a "new reader" with a post count of 1 digging up a year old thread.

I understand that. I ran across this as I searching for a roof panel for a member on the 67-72chevytrucks.com  forum. I'm more active in the truck forum.
