I am rebuilding a 350 and noticed the numbers on my main bearings and thrust bearing have the following numbers:

Mains - 18019643 - 0.0006
Thrust - GM-A-400 - 0.001

I have shopped for new bearings but could not find any with those sizes can i just use STD main and thrust bearings or have to buy a STD set and an .001 set to make it work? I dont want to have to take crank in to get mechined due to finances. thanks in advance for the help.
