Looking for a set of Crankshaft bearing

For 1975 911s, I am still looking for a set of Main Bearing # 91113360
That was the exact bearing numbers I found when tearing down the engine.
So far I have not found the exact 91113360 anywhere. If you know where or you have
a set sitting around please let me know. I do not think 91113360 is a mis-typed. If so please let me know. Thanks

Try Supertec Performance. They have an incredible selection of odd/rare bearings.

supertec@earthlink.net

BTW: I think the bearings you're looking for are 911 101 133 60.
Aline bore bearing for late 2.7 engines.

The 75 is the year they changed the tab from one side to the other on the mains.
It was a mid year change.

Thank you so much guys. I have been hunting for these bearings for 3-yr. Bought one sets from Pelican but the tab is on the wrong side so I returned.

" Main Bearing # 91113360" Jim is right. 911 101 133 60 is a line bore 2.7 bearing.
The 911 in the part number denotes late. Early concentric tang would have a 901 number.

We have them on the self ready to ship.

FYI: we also have 2nd over (.50mm) line bore bearings for late 911 2.7 cases. 911 101 133 ?? there is no part number because Porsche never made them.
