The Mustang is a car with such a huge enthusiast following that it surprises me anyone would come onto Yahoo Answers for this. Anyway, one thing you could do is register on www.corral.net/forums
and become a member on there. It's free and it's one of the oldest, if not THE oldest, Mustang websites on the internet. The site has a Windsor Engine Parts forum in the Classifieds. Check it out.
