I have Mk2 Polo bits that look like they will make great replacements. Before I fight with these Rusty screws with the dremel, would anyone know what size the self tapping screws would be? I am considering just buying some stainless panhead ones from my local Toolstation. I just can't visualise what size they would be. Probably standard self tappers found on most VW's. This will be made rust free later on as long as it passes M.O.T in a month..
