From the email I had the pertinent section is as follows
"....We can make new hoods for the Aeros but I’m afraid that the original glass cannot be re-used and replacements are not available. The problem is that the glass was originally prebonded into a section of mohair hooding material which was then used in the construction of the complete hood. It is not possible to cut out the old glass and rebond it into new Mohair – it’s a specialist job requiring specialist equipment and the company (BAS) who did the job originally for Morgan have no interest in remaking these sections of the hood........."
May be worth a direct call to BAS, they were very helpful to me when I needed to buy some Mohair direct, the chap certainly knew of MMC when we chatted & said they had cut off links to them as unhappy with some factory trading ethics
