So, last night I ordered this headlight bucket:
H4 Black Side Mount 6&1/4" 6.25" Head Lamp Headlight Assembly
Apparently its a tiny bit smaller (OEM is 6.5" I would assume), but it works just fine with minimal modding. For now, I think I'll just throw a standard H4 bulb in it, but down the road I'll be looking at that LED bulb that Old Mechanic posted up. It looks very nice.
I think I even have a pigtail for an H4 bulb from a wiring harness from a car I scrapped out a couple years ago.
