That's really good stuff about the 357 clutch being a washer less direct fit.
I've been using clutch washers from a 36 Husky. They're a bit thicker, not quite as big OD, and have a smaller crank hole that needs to be opened up, but work fine with the 262 clutch once the crank hole is modded.
Now that I'm out of 262 OEM clutches, I'll try a 357 clutch on the next build.
Good info newbie.
