He just bought the wrong year bearings . . . nothing special about your situation, you just need the 39-48 style rear main. All he had to do is look at the bearing tang width in the block and cap - to know he had the wrong one.

IMHO: Since he (or the crank grinder) bought the wrong bearings in the first place, he should be the one who is buying the replacement rear main.

To the best of my knowledge, there is no 90HP crankshaft that would have EVER used the bearings the crank grinder supplied . . . so hopefully they're not making some claim along that line. The 49-53 engines all used the 'new' bearing you took pictures of - regardless of displacement or HP ratings.
