Yes I meant WD-40.
Using white lithium grease to lubricate the new journal instead of Molly should be fine. I don't like lithium because under heat it breaks down quickly. Molly is my favorite because it holds together for building because it takes the punishment during engine re-building/lack of lubricant during start up.
Now did I miss something?
You had a bearing go out that gouged your crank that
YOU ground out meaning that you (AKA)
ground the crank making it smaller. Now add a OEM connecting rod and that should equal a larger gap. An over sized bearing is bigger thus giving you a smaller gap (taking some of the gap out).
Connecting Rod
Journal
Diameter 50.992 - 51.008 mm
(2.0076 - 2.0082 in.)
Bearing Clearance 0.015 - 0.055 mm
(0.0006 -0.0022 in.)
Service Limit . . . . . . . . . . . . .0.127 mm (0.005 in.)
From the look of your plasitagauge you are too loose thus needing a over sized bearing. you are showing a .007 gap with a needed .0002.
Basically, .007 is a bigger gap than .0002 so that a larger bearing (over sized) is needed to take up the slack bringing it back down to .0002
I think you have the decimal in the wrong place?
