Griffin Radiator has one that looks original and bolts in like original and is aluminum. Or so they say, I am interested but want to see at least a picture of what I will be spending my money on. I called and asked if they could email a picture, they said all they had was the engineering drawing. I have yet to get it.
I will try again, but if they can't show me what I am buying before I hand over the money they don't need my business.
