Clyde,
Having just returned from speaking to Matthew, the proprietor of the trimmers Strong & Turton (
www.strongandturton.co.uk) about this, he did offer the opinion that many of the new hoods he makes up to replace such unique efforts as is being proposed here are extremely difficult to get to 'look right'.
He seemed to think he would go down that road with great caution. By the way, these people have done quite a bit of carpet/leather/general trimming work for me over the years on several cars and have always done a good and not over-priced job. They prepare all the cars that Frank, Dale, & Stepson (which is next door) sell.
