May be better than you think. As long as it didn't beat the splines up. You are aware that some years with the ubolt holders were ******** that had larger caps than the standard 1330 joints. I think the caps were 1.125 in diameter. So it looks like a conversion joint. I beleive it's also a little wider as the caps I think were also a little thicker on the end. Depending on the dimensions it's possible it could be one of those you got.
Just tossing that out there.
