I agree with everyone above. If it's a small window '67 cab, then you definitely need to go with no marker lights. If it's a big window '67 then you can go either way, but I still think the no marker light look is better. Whichever way you go, I would also make sure the grill treatment is model year correct since '67 and '68 had slightly different trim/paint options.
One other thing. Are both of your bedsides from the same manufacturer? I think I read somewhere here on the board that the '67 bedsides and '68-'72 bedsides were not made the same. I think there is even one repro bedside that is missing a subtle detail, as in the small indentation around the wheel opening. I would check both sides to make sure they look the same.
