RE: Hot TR3B & Stop Leak

Daryl, Randall et al:  I have suffered the cracking on my early 4 numerous
times.  My mechanic tells me that they almost always shortened the extension
(per Service Bulletin) although I know that doesn't help you guys with 3's.
Interestingly, the Italia had a smaller round tube extension and braces
soldered from neck to side of rad.
