Thanks for the links RnR. After some research I come to find out that they are also in 63 -64 Chevy Impalas with an automatic shift column. Research consisting of me going to the junk yard and looking at 60's cars and trucks. Most 64-66 trucks were standard and not automatic transmissions. Therefore, this piece is often not included in the turn signal assembly. The usually empty last slot position on the connector is just for this light.
