Rich:
You said something that is very interesting to me: "The cable is much
thicker, and is an alternate means of compliance on the AA-1 500 hour
replacement AD." I have used other sources as proving that the ALCOR cable
is approved for the replacement- Have you found the statement AMOC (Other
Means Of Compliance) for the cable? It would make writing up the 337 a lot
easier and easier to prove.

The Alcor cable is PMA for all the Grumman singles (plus all other carburetor equipped
singles), so no 337 is required.
The 500 hour replacement requirement of the AD is part number specific, so not
applicable to the Alcor cable.
Had the AD said "replace mixture cable every 500 hours", then it would not matter
what cable was installed.

Where is the best place to get new exhaust clamps? AG5B, stock exhaust. Thank

The clamps are all the same, from the 70's production through 2006 Tiger.
Dawley Exhaust in Wisconsin carries new PMA clamps.
However, they also will "overhaul" yours for half the price of new ones.
They clean the rust off, remove the "shim" and weld on a new one, and send them
back with paperwork. Invest the money saved in 100LL.
