I got the eBay ones and removed the ballasts. and I love them good light and les power. But they do interfere with the shop radio when they are on. but I can live with that. And they light up faster and quieter. No regrets.
I have stainless washers to protect my powder coated wheels and they work grate. Don't remove powder coat its just a place for rust to start. But in the end its up to you. :)
Cool you will love it. I love my 29 special coupe but mine is a survivor that i am the 3rd owner of. drive it every chance you get. That is the fun part.
We don't take anything with us.
