I think you counted the wrong shaft. The outer one will be the same but the inner one is different. If you look I think you will see that the '86 Input Shaft (the inner one) looks fatter (30 Tooth) than the '83 (27 Tooth). Good thing you weren't going the other way though, the converter would have gone in and not worked!
