I called them a few months ago and they verified that part number had 2.399" main journals with a 4" arm. I did not ask if it had an oil slinger. At that time they had no stock and the price was high (don't remember exactly how much) but it may be possible to get one at a lesser price if it wasn't purchased direct from SCAT.

If a late merc crank was ground to 2.399" on the mains how would one address the oil slinger/ rear main seal. There is not enough diameter there to create the slinger. Boring the mains out to use the 2.499" bearings and using a 59A rear main cap with a seal seems possible but expensive.
