Funny that the Haynes manual didn't mention using marks on the belt itself to line things up. It only mentioned lining up the crank and camshafts. My old Subie has just two cams, FWIW.
The car is still running fine and I've put 1,000 miles on it. In fact, it might be my imagination but it seems quieter than it ran before I changed the belt. (I also replaced the two accessory belts, so one of the three might have been making some noise.) However, I will check the timing belt at my next opportunity. It's vacation season for me, so it will be a few weekends before I can get to this car, and I have to do a timing belt in another car (not a Subaru) first.
Thanks for all the help and advice!
