[QUOTE=Steve Holmes;60989]Thanks to Paul McCarthy for sharing this great magazine article from 1970, showing how the Broadspeed Escorts were tubbed, as per Howard's description. 1970 was the year the BTCC switched from Group 5 to Group 2 rules, with Group 2 allowing more freedom in many areas.]

Steve, what a wonderful resource The Roaring Season is, the very same car as I was recently shown by one of the original constructors! Period articles and information such as this are a vital piece of the "evidence building" which is part of the research needed to correctly build to original specs. I guess you either love or hate that part of the process, I take my hat off to Pauls McC and B plus John McKecknie and everyone else who researches properly and is generous enough to share the knowledge.
