Cab marker lights

[C10 - C90 Bill]

Great Instruction Sheets markeb01. When I put some original Yankee 77's on my '64 C-30 back in '81, I could not find those instructions anywhere. I even called a Chevy Dealer or two and nothing. I believe they even told me that there was no such a thing. I ended up going to junk yards and measured some trucks there only to find a few different combinations. I finally used a combination of some of those measurements, by memory from my '62 GMC 6500 with factory lights, and by just placing them and stepping back to decide. Somehow it worked.

I measured my lights off an original truck and ran the wire down the "A" pillar. These lights were dealer installed when new.

FWIW, here's the GM drawing I used to lay out mine. Found it in the '65 truck information kit on the heritage center website. http://www.gmheritagecenter.com/gm-h...tion-kits.html

I used the LCF/Conventional layout, BTW. Here's a little better picture of the lights
