Hi David,
I have some suggestions which you might like to consider.
1. Post your request on this forum again but into a more suitable place than New Test Forum. Perhaps in ' 6 cyl Bristol cars ' category.
2. Go to the websites for the BOC (
www.boc.net ) and also BODA ( [url]www............org ). Between the two clubs there will be events which suit your possible dates. The web address of BODA refuses to be shown here. You can google it.
3. If you are not already a member, and if you join both clubs, you will be able to access the membership lists to see owners of 403's and 401's. I'm sure that the technically minded owners would be glad to help you.
I have owned a 403 for 16 years. Would be pleased to let you examine my car for ideas if it would help.
Dave Dale.
