65 vs 66 backup lamps
 

Would anyone have a picture illustrating the difference between the backup lamps on a 65 Bonneville/GP/Cat vs 66 Bonneville/GP/Cat?

There may be a difference, but Ames Performance sells a backup light assembly they say is applicable for 64 to 66 full size, except the 64 GP.

Interesting. I think the GM parts book says they don't share the same part number but they sure look like they could interchange.

Anyone have experience with swapping them from one year to the other?
