Got a pair of spiderweb Chrysler Airflows for my A, reasonably rare and bloody expensive, but man they are the coolest lights..
$2.00 tail lite from swap meet mounted on spare tire mount and third lite in back window, late thirties Chevy turn signals on each side
Friends 35 Master Chevy sloper (All enclosed coupe) with 37 Chevy tail lamps and I believe, 35 Ford bumpers
These little Zeppelin shaped guys came on my '26 T roadster, they were home made by the previous builder. It's a shame he let them get rusty (along with the rest of the car), but that will be rectified in the rebuild.
The "late thirties Chevy turn signals" are actually 39 Chevy taillamps which were also used as accesory taillamps on 40-48 Chevy/GMCsedan deliveries and panel trucks up through 1954.
A little hint, if you want to keep your tailend from being eaten by a Subaru remove the lens and mask off the bulb socket with masking tape. Paint the inside of the housing with gloss white enamel. Wait until it drys, remove the tape and reinstall, bulb, lens (after scrubbing with dish detergent and a toothbrush inside and out) and rim. Put on your sunglasses because your lights will be really bright now, day OR night. The entire lens will be lit up as opposed to only the part directly in line with the bulb element. You're welcome.
I am going to use 54 Buick tail lights on my coupe but they look a lot like the '50 Pontiac but they are more pointed. sorry I don't have a pic of them.
