If you look at the pic provided it shows a STD on the back of the bearing in the pic. Its sort a hard to see but this indicates this crank is at standard size.

I am not sure you need plastigauge at this point to measure your old bearings, they are worn out and needing replacing. Take your crank to the machine shop of your choice and either they can polish it or turn it based on the wear the crank may have. Ensure you have your rods re-sized as well with new bolts. this process trues up your rod bearing cap to ensure proper bearing clearance. Its part of rebuilding the engine.
