Yes, that's the doweled upper bearing. Finding a replacement for that one is going to be difficult, if not impossible. My Federal Mogul shop specifications manual confirms that you've got an .010" undersize crankshaft. That bearing is in terrible shape- - - - -definitely Do NOT try to reuse it.

The Federal Mogul part number for the bearings with the upper dowel is 853M-10. If the engine is completely disassembled to a bare block, the later style bearing set, 960M-10 can be substituted by filing grooves at the parting line for the locator tabs for the later model bearing set. Those bearings are expensive, but at least they're still available from most sources.
