340 crankshaft info needed

Thanks gear and Jos

I used the link and got the part number for the national bearing FC69907. I will have the lady grab one at work, since i'm on vacation, and the project will continue!
I just took a rough measurement on the depth of the current pilot hole since the engine stand in the way of using a mic. I get a rough depth of a hair over 2.5in which seems it should be deep enough to fit the input shaft w/o modification?
