Ooh, I don't have the gear wells, are they worth looking into? I think I'd just carefully scribe away what I need instead of taking a motor tool to it. Just make sure to leave yourself a margin of error and finish the fit with sanding instead of trying to cut to the right place. Cut close, not all the way.
The Seamless Suckers was hard for me to track down, but I eventually found a phone number on the internet. A guy in Kansas runs it from his house and usually makes the stuff per order. Lemme see if I can track that number down and give it to you. The exhaust is about 10 bucks, plus a few for shipping. He's a really nice guy and will send you a price list. He makes good stuff, that intake looks really nice dry fit into the fuselage.
