I'm thinking that is most likely what has happened. I'm going to to a proper measure of the stroke tonight though - just to confirm!A quick check in the spare parts list for 1959 88 and 99.
Crankshaft different stroke, pushrods different length, barrels and pistons different. The rest seems to be the same. Might have missed something.
So to be certain, you have to measure stroke.
It could be that PO found that max overbore .060 was not enough so he had it rebored to 68mm and threw in 99 pistons.
