Crankcase bearing stamps

[Sam]

I'm trying to get the correct bearings for the crankshaft and i've read that there are supposed to be markers stamped on the bottom case. I can't seem to find it (cases are clean and i have been looking for two evenings!). Anyone have any experience with this? For the record, my engine is number 1629.

Thanks!

Here is the place where marks are struck.

Very helpful pic and totally explains why I can't see mine; that area was broken off by a previous owner! I had my welder fill it back in, so those marks are forever gone now!

Off to buy a boar gauge and do this the old fashion way.

Thanks for the help!
