Chris,
Can't help with your problem but was interested to know if you found any useful manuals, CDs etc.
I have a '71 250CE with a rusty floor and a '73 250C with a clagged motor. I'm in the middle of pulling the CE engine to install into the 250C car. As you might have guessed this is proving to be something of a mission and any info would be equally desperately appreciated.

Regards,
