Mine was a semi-flot 6 lug with MarkWilliams 1.5" 35spline axels stuffed in it. I bought the rear end that way. It came out from under a K20 that was getting Rockwells put under it so I can't take the credit for building it, well I did add the Powr-lock and 4:11 R&P...
It never broke and was still in great shape when I sold it.
