I was reading the article “ Healey’s Six-Slug Slugger” in the Austin Healey Magazine and one thing caught my eye. Towards the end they mention converting to full disc brakes, noting kit #H8462 for the rear. Anyone know anything about this kit? Was it from the factory? The conversions I’ve seen photos of, there was grinding of the axle to get the caliper bracket to fit. I’m wondering if H8462 was a direct bolt-on. I’m curious if the parts list mentions it and what components used were(note to self: I really need to get one of those lists).
