didnt fit any boss, just drilled the victa discs to the same size centre hole as the bar blade which was 7/8th andd fitted with the standard murray centering washers
it actually worked quite well as far as a much better cut and cleared the cut grass out the chute much bettter but the mulching discs seemed to cause a bit of vibration but that was probly a blade trimming issue
