I wanted to go look at a couple of projects recently, but a POs had removed the drop rails so I declined. Yea I could obtain drips rails and reattach but I said screw it. I had a 71 Demon once a PO had removed the drip rails from, WHY I have NO idea. The only damn thing he did to the car good or bad. I an see drip rails maybe being an issue with the cars that came with the cursed vinyl tops though!
Like said make the car like you want but remember if you ever sell, anything you do will be either positive or negative!!
