I bought this on Craigslist a while back and recently put a full grille set in. I was gonna sell it and I have no clue what brand it is. It was polished I painted it black. Pics are looking from top downward so you can see the curve in it.

 

Not sure. Maybe you could figure out a way to graft that onto the Lotus somehow?

 

LOL, That darn car's got enough grills in it, Good workbench though (It's getting painted or I would never have done that)

 

No idea who makes that bolt on grill, but most of the "generic" aftermarket stuff like that, just post a picture and call it a "billet" grill and it will find a new home quickly
