First off , welcome to the forum Larry. It's great to have you here.
Good lookin' project you've got yourself going here. . I will say that you're in for a wild ride with this build. I just got through with the panel wagon/ sedan delivery version of this kit and it has no headlamp or tail lamp bezels. I managed to pick up an AMT 51 Chevy to rob the headlamp bezels from and ended up Frenching those into the body.
Here's the kit I used:
What I started with:
I block sanded it from the front and made the opening larger so I could insert some headlight buckets/ bezels into the cavity to have a mostly flush mount between body and bezel.
Here's the openings after I got through block sanding them down:
and after I test fitted a bucket / bezel in:
NOTE: This is a perfect shot of those nasty hood hinge openings too which I filled in with black sheet stock from Evergreen shown in the pic above
Here's a pic of the headlight bucket openings and the now filled in hood hinge openings.
A little bit of sanding later and you could never tell they were there................
Hope this'll help you out some.
