Marker Lights
 

BEFORE YOU ALL FLAME ME, I'M PUTTING A 67 NOSE ON MY 72
WITH A COWL HOOD, I WILL HAVE A 72 BUMPER UP FRONT &
A ROLL PAN OUT BACK. THE QUESTION IS SHOULD I LEAVE THE
REAR SIDE MARKER LIGHTS? IF NOT, DOES SOMEONE SELL PRE-
FAB BLOCK OFF PLATES FOR SMOOTHIN OUT THE LIGHT HOLES?

I would block them out to avoid hassles with the cops complaining that you are "missing some lights on the front" and just for esthetics.

If you are capable of welding in plates to cover to rear marker lights then just make your own. Take a piece of cardboard make a template, transfer it to a sheet of metal and cut it out.

I am in the process of doing the same thing weld em up..

Like this..

weld em up. BTW the 67' front end looks way too cool on the blazers.
