Lucky enough to receive a hand me down Case 444 with a J80 snowcaster from my Dad. The blade fell off so reinstalled it. It’s the original so has some serious wear. After reinstalling, the bolts stick down lower than the leading edge the blade and touch the ground first. I need to find 3/4” carriage bolts instead of the 1” ones I currently have. I don’t think that’s going to matter much though. Can someone confirm that the correct replacement blade is a C17878 and a C17775 skid shoe?
