ID Wanted turn signal switch 65 GMC

[Vernski]

This is a GMC specific part, 4-5-6 Chevrolet is not the same, A 63 Chevy will mount up the same in the signal cup but the color code is wrong. The GMC part is made by Boyne #on it is 803 I would like to find an original part for it. I fixed it by using a 65 Chevy signal cup and a 4-5-6-chinese turn signal switch.
The OEM switch was made of metal, the chinese switch is all plastic and I wonder how often I will have to replace it thanx...Vernski
