So I changed my 99 Forester clutch slave, hose, and gaskets as reccomended in the TSB to the newest numbers.
The clutch was still inadaquate as it still would catch near the floor and clunk back when hot in heavy traffic.
I changed the master cyl and now it acts like it should.
This makes me wonder if I really needed to change the slave and hose, but frankly it makes me feel better.
The car has about 95,000 miles on it and since the updated clutch was installed at 89,000 the linkage has been getting progressively worse.
By the way the new clutch still feels fine.
