Kent, the NOS hood trim along the front went for a bunch of money, didn't it?
I seldom see the hood trim for sale.
I see the '68, '69 and early 1970 grills and headlight bezels quite a bit on eBay.
Be patient.
It should get a tad busier after the holidays.
If I happen to see a grill around here for sale, I will let you know.
I just traded a set of front 1968 Falcon Sports Coupe bucket seats for a grille and headlight bezels to a friend.
If he or I run across another set, you will be the first in line to know!
I do not think a '68 Mustang windshield will fit a '68 or '69 Falcon.
Some of the glass companies that have been in business for a while might be able to help you out on that.
I found a NOS early 1970 Falcon factory tinted windshield for my project car a few months ago for $75.00 + shipping.
I have factory tinted glass all the way around for my project Falcon.
If you went with a '67 Falcon grill you would also need the '67 headlight bezels also, wouldn't you?
