I submitted the TSB this year again as the SEB has changed a lot since the
last time I submitted it (10 years went by fast!).

OK, then how about the Camaro aluminum 1LE driveshafts which are
ALLOWED to be installed due to a TSB but not required? That does
not seem consistent.
The difference in the Porsche tensioners vs crash bolts/subframe
connectors/
driveshafts is that NEARLY ALL street driven 911s have these installed
already. In a quick lookup in street cars for sale in the national PCA
magazine,
5/99, page 88, '70 - '73 911s, out of 12 stock cars for sale, SEVEN
specifically
mention "carrera" or "press fed" or "hydraulic" tensioners. Many of the
others
probably have them too, but not listed. So anyone buying one of these
cars could not run it in A-Stock or ASP (I run my PCA E-Stock 911RS 2.7 in
AP
though it is not as fast as a good ASP 911).
I don't see why a factory TSB that allows a non-performance item to be
fixed should not be allowed in stock class when every dealer and
repair shop installs them, and other TSB items such as driveshafts are
allowed though not required.
