as i have sooo much time, i thought i'd share this with you. Firstly get a knackered old kombi, i found this in my drive way. Strip it and gut it, try sell off as much as possible, it saves putting it away! cut the roof off, i'm using the back end, so i only cut the rear section off. now cut it in half, alot easier said than done, but i did it! REMEMBER, measure twice and cut once, wild guessing twice is NOT measuring. i have screwed up but its not all bad!
