Here's the headlights. These use the plastic Wipac headlight buckets. I know in the past the headlights protruded out a good bit and made the headlights look "bug eyed". I believe the headlight buckets were metal. These fit pretty well as shown.
A warning -- I made the assumption that the headlight buckets fit with the screw for the trim ring at the bottom. Nope, it's 5-10 degrees rotated. When I installed the bulb it was rotated and the lettering on the bulb wasn't level. Had to redrill the holes to rotate the buckets. Not an issue as the buckets covered the old holes just fine. So I suggest you fit the bulbs to determine the proper rotation before drilling the holes.
Also, make sure the wires for the headlight go the proper terminals. There has been discussion on other threads on this forum about the proper terminals and what is in the manual is incorrect. There is a US version of the headlights with one terminal configuration and also a UK version that is different. If you
use standard headlights, then use the US version and if you use the Lucas headlights then it uses the UK version.
I used 10-32 x 3/4" stainless screws with flat washer and nylon locking nuts to install the headlights and the marker lights.
Here's pix of the headlights installed and the wiring on the backside.
