Main Bearing replacement guideance

Yes....
The Oilpan meet the bridge deck down the road from the house.
I was logging my FAST EFI when it happened and the oil pressure dropped to Zero when the two meet.
Then slowly came back up some as I drove back to the shop. Plus the bearing clearance was on the loose side to begin with.

If you cannot find the full groove set, you can use two sets and use the uppers in the main caps. You'll have to modify the bearings I believe as the locking tabs will be on the wrong side, so you'll have to file them off. You can add new lock tabs in the appropriate places if you want, but it's not necessary, as the bearing crush will keep them in place. I've always added them anyway in the past when I've done that.
