I should thank you for posting, as I need to go find mine to reinstall my clutch when I get to that point.
Amazon also says that the Dorman 14522 Clutch Alignment Tool doesn't fit my '51, so it wouldn't fit your 55.1 either.
You can measure your transmission input shaft to see if it'll work. You'll need pilot diameter (and length, although that's not super critical), spline overall diameter, and number of splines.
My transmission is accessible and I could measure for you if you aren't able.
