Escort seats in a 65 Mustang?

[LuvMyStang]

I once heard that Escort seats were a direct bolt-in to the early Mustangs. Anybody ever try this? I've decided to start going for comfort in my 65 instead of trying to stay original. I want something with side support to keep me from sliding across the ol' vinyl seat on every turn, but don't want to spend a lot of money, so I thought I might hit some junk yards. If this is possible, does it include all years, or just certain ones? Thanks...
