86 Cutlass supreme 4 door left turn signal assembly. Mounts from top 3 screws. See photos thanks for looking, Perry

 

I have some G-body parts. What is the part number molded into the housing? Thanks, Bob.

 

It can be either one, as it doesn't have the Fibre optic feature Gm 5935051 2a or Gm 5933849 2f.

 

Is the supreme G47 or 69?

 

G69 is 4 door.
The first casting number is 5935015. I think you have a typo.
Casting number on part may be best to go by for used as hardly anyone would know the catalog number for a loose one.

915807 for LH
Apparently they're hard to come by based on asking price!!!

Too bad it's not a coupe. I've got a set of new + used. They won't fit your car, though.

 

Well I have found a good used one that will work, Ebay, thanks for everyone's insight, Perry in Michigan
