Yep just looked a little deeper the inner bearing doesn't fit the spindle either. Not sure how this was working? What about running the taller 73 and up spindle? I have a set of those and I have 4 of the 11" big spindle rotors.
I ran into this when putting discs on the front of my Savoy luckily my parts guy was a stock car racer and knows how to put stuff together. I didn't really know what I had because got a bunch of parts in a milk crate from a Toyota customer of mine. I would start from scratch with the tall spindles and 11" calipers. We have a bearing distributor near me in Akron and there is a girl that works there and she carries a set of calipers on her belt to measure your bearing or seal needs. I prefer to deal with a bearing and seal specialist when putting things together that you really don't know the origin of
