That kind of document would be great, but there is no cooper mk3, it has to be pretty specific to be acceptable. Even some book or brochure that mentions that both cars are ADO20 would help.
Wikipedia or www page is not acceptable.
Repair manual, brochure, book etc. Scanned pdf, or even picture will help.
Edit:
Anyone have British Leyland: The Cars book? Is there that kind of information?
Or any other book to look?
Thanks!
