We raced on it (4:10 welded spiders) to save 100 (iirc) lbs of unsprung over an 8&3/4 & it held up well till the car was wrecked & broke an axle & yes the wreck broke the axle (& more) not the other way around. A consideration was to switch to SBP if that would ease my search for a replacement as I have SBP rims available. With no interchange I will continue searching for a BBP replacement axle. Thanks guys.
