I believe Jim Cowles
www.shelbyparts.com still has some 6-bolt Cobra lettered scattershields as used on R-Model Shelbys. The guy that cast them did the last run of them several years ago so they are getting difficult to find. They are really cool looking and add a little security over the cast aluminum bellhousings.
He also has plenty of blocks. Obviously the distance is a little further to Green Bay, WI, but at mininum you could take care of the scattershield with him.
