Why don't you just measure the stock ring size? Anywhere around that should work.

 

You're right 180 is too expensive.

I priced out custom headlight work for my 11 g37 sedan using his prices and the total came out to $760. That doesn't include shipping.

That's only for

Opening lights ($100)
STI-R lens swap ($150)
Gloss housing ($200)
Eye lid ($150)
Projector shrouds ($100)
Gloss black amber reflector ($60)

His prices are ridiculously stupid. I'm sure he does good work but I'm sure as hell not paying anyone $760 just to paint a couple things in my headlights.

I got a vendor on my acura forum to do my headlights on my G for me. I asked for exactly everything I listed above. I also got my headlights refinished and sealed with Lamin-X film.

Total price? Around $450 Including refinish lights and applying lamin-x film.

Without headlight restoration & film installation it would have been around $300.
