The bearings for the late model 235 will be Federal-Mogul part number 960M or an equivalent part from another manufacturer. I believe Sealed Power uses the same numbering system as Federal Mogul. If you happen to have the block with the locating dowels in the upper bearing, the F-M part number will be 853M. Those are the scarce ones. It's possible to modify the early block to use the 960M bearings, however.

There are several sets of 960M-10 bearings on Ebay at the moment. For instance:

DO NOT RELY ON THE DATE OF MANUFACTURE TO ORDER THE BEARINGS! Physically confirm that the upper bearing shell locating tabs are at the parting line where the main cap meets the block! BOTH sets of bearings have locator dowels on the lower bearing shells.

Yes, a reground crankshaft needs undersize bearings, since the shaft is ground to a smaller diameter to compensate for wear and make it round again.
