Why don't you drive over to me and we'll do it in the garage where it's warmer. A retrofit should take no more than a day. I've gotta do work on my headlights too.
This is an incredible write up and awesome job on the build. You are exactly the type of person I would buy a car from. I just read through the entire thread. Very good job. I do love the wheels you're going with too. Good choice !
