Wilwood kit install for 9” drum spindles

Thanks. Sounds like they don't tell you about the requirement to grind your spindle and otherwise mutilate factory parts. If one has the option, I suggest changing to 10" drum spindles (different Wilwood kit) since they use larger bearings. I had both little outer bearings (Timken SET1) in my 1969 9" drum Dart fail. The race spun in the hub, ruining it. Both were well-lubed. Indeed, one failed 200 miles after a shop changed both on a cross-country trip and I watched the guy change them correctly. The other failed 3 yrs later, the same way.
