Didn't realize you were in the Netherlands. You're a brave soul for taking this on. I take for granted the availability of local salvage yards, especially the ones that are Mopar only.
If you're paying in dollars or plastic, I don't know why they wouldn't ship to you. There may be some issues with import duties that I don't know about.
I've actually restored 2 66s. The first was a 270 model 2-door hardtop with a V-8 and three-on-the-tree. The second was the GT pictured. It was a very early production 273 HP with automatic and factory disk brakes. Naturally, here in Texas both were air conditioned. The 270 had an aftermarket system, the GT was a factory install.
