Looks like you've had your share of problems with this kit, Tomcat. But being creative is what it's about. Your solution seems to have worked, and unless you hang it up, won't be noticed anyway. If you're insterested, here's a link to my kitbash of the Monogram UH-1C/Italeri UH-1D into a UH-1F: https://www.scalemates.com/profiles/mate.php?id=28001&p=albums&album=42471#18 I had the same problems with the bottom seam of the cabin, and as noted before, trimmed the floor and rear bulkhead to fit in. I replaced the rear bulkhead with pieces from the Italeri kit, since I was putting the minigun ammo cans against the wall, and didn't want the curtains on the Monogram casting. There's quite a gap between the bulkhead and cabin sidewall, but wouldn't be seen because the open doors would be covering it. Since mine is an on-the-ground presentation, the pilots are not in the cockpit. The miniguns are from brass castings with brass ammo feed lines. The minigun mounts and frames are scratch-built.
