I have seen a lot of front end treatments and have come up with a plan (on paper for now) how we are going to proceed...
we are going to eliminate the lower grill, use pre'74 turn signals and pretty much duplicate Alan's sheetmetal spoiler/front/ dam or whatever you want to call it...I am not a big fan of the curve in and then out again look of the bolted on front spoiler...just my personal taste
I really like the look of Alan's work (don't laugh at my rudimentary photo editing)
Alan's:
with a little editing
so we will have the pre '74 turn signals and probably add two 4 inch round intakes somewhere in front (flush mount) with chrome rock guards...these will direct air via tubes (sort of pseudo fog lights), one to oil cooler and one to cold air box for dual webers
now if I had an unlimited budget and/or mad welding/auto body skills I would fabricate something like the next picture...I added the front end stuff and two tone (our color scheme of choice), the spoiler is from an old Datsun 2000
will be interested to see what you end up with
