Nice... so they are drop in replacements!
Post pictures when you're done and do update us on how things were improved. Make sure you aim them properly... aiming them using a cardboard is easiest because you can move the cardboard instead of the car more easily.
What brand are these 5.75" units that you're getting from the local parts shop?
I'd sink more money into Hellas and Cibies just because....
but that's me..... what I kinda want to do now is put in 7" Xenarcs (6024 replacement HID's) in my US headlight assembly..
I wanna get an R107 too.. damn.. love 'em roadsters! Definitely some classic!
