Chrome Overlays for Replacement Towing Mirrors

[GeeJay]

I am planning to replace the DL3 mirrors on my new 2013 Sierra SLT CC.

I also want to fit Putco 401273 Chrome Sierra/Silverado Towing Mirror Overlay

I know these Putco parts were designed for the GM Towing Mirror # 19243900 but I am looking at lower priced copies of the GM Towing Mirrors such as Fit System 62093-94G or KSource 62093-94G.

Has anyone installed the Putco 401273 kit on the 62093-94G mirrors and how did they fit?

Thnx

GJ
