Hey Tim, long time no speak!
There is a guy from Birties forum who is selling the shell of two FSJs at the moment. He's close to me in Derbyshire, I actually went to see them a few weeks ago.
I didn't pay close attention to the roofs, but he had a 2dr and a 4dr Cherokee. The 2dr certainly looked rescuable to me.
All the details are in a post in "Exchange and Mart" on Birties, his forum name is jeepdog. Having said all that, you'll probably say that you've already been in touch with him!
