Jim's website is advertised on the main page of MGB and in the links section. It is Performance Graphix...you can contact him through there. He will most likely reply to this post when he sees it though...I know he is out of town for about a week or so though, so give him time.

Keep us posted on your boat..looks like a cool one!
In the meantime, can you post a picture of the pullstart? Might be the same we commonly use. Also there is a short article on the main site here on how to recoil the spring in one...might help.
