Re: 67-72 GMC Grill differnce.
I'll attempt to stay on topic here...one oddity that I noticed on my 69 GMC is that the marker lights on the bedsides and the front fenders are inoperable on all GMC's and with Chevy's they light up. I don't know if this changed after a certain year but I was amazed when I pulled the cover to change the bulb on my truck and there was no wiring behind, they are just reflectors. Can anybody confirm the year that GMC went with lighted markers?
