They're more than welcome to get in touch with us - clutch parts for these cars need to be chosen with care by companies who work with the people installing them for feedback.
We deal with the trade all day every day, and we put an awful lot of time and effort into getting parts 'right' for these cars, and investing more than half of our profit back into production of hard-to-find parts.
Just as a side note, our email address and telephone number should be on the bottom of the email - and if not, any link you click on the email will take you to our site with both in bold text at the top of the page
