I spent several hours hunting info on an actual 5x7 cibie headlight that would mount on a stud or bracket likely as the ones in the old cars did in the day all I am finding is a "driving" light not hi/lo true headlight like a h6054.I did learn that in the vw dune buggy world they "did" sell a rectangle bucket for the 5x7 true hi/lo headlight but can only find those at the moment in 4x6 for like a H4666 true headlight.
The euro market might have something.
I am going to talk with mike about a fiberglass 5x7 headlight bucket.
At least that one motion mako has 63-67 style front turn signal pods molded in...
