I've finally gotten around to deleteing that ugly E.T. light on the back. I've always hated it. It looks like an afterthought. I know it has it's defenders but, whatever. Anyway I got the 993 basket handle spoiler from AASE. 309.00 as apposed to over 1000.00 from FVD. The body shop has painted the basket handle and it's ready to install today. My question is what's the best way to deal with the hole left from the periscope? I seem to remember some kind of plug. I know it's a common conversion so does anyone have the answer? Thanks and I'll post before and after pics when it's done.
