I had someone restore the lines in my 78 351m that some kid took off a year before smog...not me of course. Anyways, the mechanic knew he was in for a task and his BEST resource ended up being some photo copies from a guy out state. I would start looking around for someone with the same truck and make it worth his while to stop by for a few hours if youre not facing some deadline. Sorry if my suggestion doesn't satistfy. Those diagrams are hard to come by.
