My old magneto drive cushions from my O-540-A1D5 with slick mags are breaking apart, they are LW-13641. I couldn't find this style on Spruce, only the new style with tangs, but I noticed I could order Superior SL-13641 cushions. The page doesn't have a photo but I assumed incorrectly that the old part number meant no tangs. Can I still order the old style somewhere? Do people use the new style and cut the tangs off?
