James Duff does not give their email address, on their web site you click on CONTACT US and it will take you to a form where you fill in some info and submit it. I am sure that once you got a reply from them in your email then you could find out what the actual email address was by looking at the properties of the FROM box on the email. Sorry I do not know much info on a floor conversion for a 6 cyl. I have done one on a 8 cyl and it was actually pretty simple, I would not think that doing it on a 6 would be too much more difficult. Wild Horses web site says that their conversion is designed for a V8 but can be modified to fit a 6.
