Hi Eric, Well I'm really don't blame you for the Euro, I just like poking fun from time to time. Not very good at attaching links so try this
www.craigslist.org then choose to search for boise, idaho then my seach found the engine listed under 1965 ford
this should bring you to the ad. the respond to email address will be at the top of the ad. Let me know if this works or doesn't, If necessary, I'll contact the individual and try to arrange contact between the two of you. What color / body style Mustang do you have?
Mike Street, Boise, Idaho
