Difference on crankshaft bearing 2.7 1975

Hello all!
I am assembling a 2.7 engine on a blank case.
When ordering the crankshaft bearing shells, I have noticed that during 75 there are two models of bearings - from engine 615 0306
As my case is blank and there is no reference number to know which year it belongs to, can someone indicate the difference between both examples?
Thanks for any help.

The change had to do with the oil bypass in the case
The difference in the bearings is which side the tab is on,
Tab to the right or tab to the left.

Thanks for your help! And do you know which situation is the earliest? Left or right? Thanks!

Bearing tags

All mid75 and later through the 90s are tagged to the left.
