Ok i measured the bearings and i understand my case is .20 and crank is at 1st cut. Now i need to figure out the thrust. Its at 21mm but is that .20 or .40? Just a little confuse since i want to order the right main bearings.

Are you sure?
In olden days they did not make that size
1mm is .0394"

the part number for .5 OS, .25 US, 1mm over thrust would be
111-198-473OS

I measured the #1 main bearing's thrust and it pops up .825''. I measured the case saddle and its about .830''. So basically i just need to figure out what size will work. 1.00mm thrust will work fine?

.875 is about 21mm, so it would seen you are correct

Alright its 1.00 mm thrust. Thanks.

some shops would cut the thrust just enough to clean up the case and machine down the bearing to fit.
