Now that I have a plan, it looks like I need to get a couple of the Eurospec Cibies to stand in until I can take the time to remove, disassemble, refurbish, and reinstall the Z beams.
With my 175s blocking the grille mounted park lights, I had planned to run small LED type park lights where they aren't blocked. How bright and usable is the park light feature of the E code headlights? Are they a viable alternative while I have the E codes installed?
Completely! But they are parking lamps only, not turn signals. Sounds like you might need to either move the 175s elsewhere or retrofit some turn signals elsewhere. A set of the valence-mounted items used on '61-'62 Lancers and '63 Valiants and Darts might be readily adaptible.
