How about using an 07-15 Jeep Wrangler headlight? Looks like it uses a 9008 bulb rather than a 9003, but you can get the wiring terminals to fit them for like $6 on RockAuto.
No idea if it even swaps in, only that it looks similar and I know of one A-Body that has them. Can't say he didn't have to do some custom work, but from the pictures I've seen they look close.
Just asking, no idea if it is even reasonable.
Thanks.
