the wrapper plastiguage comes in has marks on it. this represents the thickness of the plastic when crushed from torque specs. match the wrapper marks to the flattened plastic and the width of it will tell you your clearance.

You put a strip of the plastigage down on the crank, assemble the rod/main and torque it to spec being very careful to not turn it. Take the cap back off, put the package that the plastigage came in up against the squished piece of strip and however wide it is, is the approximate clearance.
I'm sure you could google it for a more thorough explaination if you don't understand this one.

You should be able to get them at Napa or any performance shop. Its probably gonna be like 3 bucks. Depending on what the motor is gonna be used for i would use a micrometer instead of plastic gauge just because its more accurate. If ure going this in depth just take the extra time and do it right. If you have any other questions just shoot me a pm.

No LockTite, just torque in sequence to spec. And oil the threads of the main cap bolts. < Correct if I am wrong. I done it this way every time.
Also Plastigauge is not very accurate. It is good but not great, I used it on my last few rebuilds just because I can not stand using inside and outside micrometers.
When you use Plastigauge make sure your bearings are dry and not oiled. An make sure not to turn the crak at all!
