Yes they can cut to custom sizes if they are laser it's pretty simple. Bob Holman seems to be a really nice guy to deal with. He helped me on a B-17 problem I had once and he was great. You can get most everything you need for the ziroli kits from Ziroli's website and Laser Lizard can cut the short kit. I prefer to get the short kit and pick out my own sheeting. Downsizing a kits main problem is finding the vaccum formed parts and canopies. If your into making your own that would solve that problem.
