When I climbed them, the only information I had was “The Climber’s Guide to the High Sierra” by Steve Roper. It provided the following description: “Peaks 5 through 8 are all class 3 via their northern sides.” I didn’t disagree with Ropers ratings. That was 30 years ago, so I don’t remember any details.

Note that every time some clown gets scared on a route, the rating tends to go up. The first time I did the SE Buttress on Cathedral Peak, it was 5.4. Croft rates it 5.7. The U-Notch to Polemonium Peak used to be class 4, and the NE ridge on Bear Creek Spire used to be “class 3 or 4.” Both are now class 5. My oldest guide says the Swiss Arete on Mt. Sill had a class 4 variation. Secor (3rd edition) says it’s 5.7. There is a 14er in Colorado that I summited wearing climbing boots and using no hands. The climbing guide rated it class 5. Ratings are not nearly as consistent as we might like.
