Haven't seen the picture you guys are talking about, but depending on where they are, maybe the holes in the bumper are steps so the driver has an easier time washing the windsheild?Ed -
Reviewing my post, I realized I didn't include the pic of the GL Silversides. Here's a link to the pic:http://www.norcalbusfans.fotki.com/greyhound/greyhound-mainline-1/gmc-pd3751pd4151/gl1947.html
If you go back to the 3751 page, there are a bunch of Silversides, all with various front bumper "stuff." JLV (RoadrunnerTex) & I talked about some of the "stuff" being steps to clean the windshields, some being holes for additional fog lights, etc. But note that some w/ bumper holes no longer have the OEM fog lights. . .http://www.norcalbusfans.fotki.com/greyhound/greyhound-mainline-1/gmc-pd3751pd4151/#media
As Buswarrior says, each shop does it's own thing to keep the fleet moving. . .Mark -
In my conversation with JLV yesterday, he said that Fred Rayman seems to remember that yes, those stripes were reflective 3M ScotchCal, and that some ScotchCal was also applied to the rear engine hatch around the center target stop lamp. . .Tom -
Yup, I know all about the "crazies adhering to OEM" crowd from marque auto clubs, especially at concours events. Sometimes I wanted to wring their necks with a broken Corvair fan belt due to their occasional lack of common sense. . .
That's probably what makes this hobby so much fun - it's really a "Do It Your Way" mentality, as Fast Fred so often says.
FWIW & HTH. . .
