Want to Install Single DIN Alpine in 2005 987

[PartialFish]

Most people who convert want the double DIN. Well, I already have Alpine's best single DIN, the 9887, leftover from when I was going to put it into my old car. Then came the Porsche. The Alpine is iPod ready, and I don't care about navigation (anywhere I go in the Boxster is ok!) Obviously, I need a single DIN mount for the new unit. The eBay ones I've seen are double DIN. Worse, I'm in the middle of Missouri, would probably have to go to St. Louis or Kansas City to get this done right, esp. if it's a fabrication job. Also have some Polk doorspeakers and a better Alpine amp. I'm up for suggestions, and would appreciate any thoughts. My present setup is the upgraded non-Bose audio system, which if fair for an open car, but the head unit sucks, and I know the stock speakers can be improved. As best I understand, there's digital cabling in there, and I'd better find someone who understands all that.
