Thanks for the tip. I just ordered them and have been looking for something for those windows forever. I actually started mapping out plans to create my own photo etch for them. Now I can start working on it and worry about some kind of engine insert later.
I've got a tub filled with old pens that I end up using for building alot of things. They can be a great asset for all kinds of cool extra bits that you need along the way! Great idea bro!
