NH 275 part numbers

Hi all. Just wondering if anyone could tell me the genuine part numbers for 275 shear bolts, both flywheel and knotter. Also drive chain number. I can find in here 270 and 276, I am sure they would be the same right? I checked out Messicks online but it would kill me in freight at the moment to get it over here. Look to be about 5/16 and 1/4 diameter bolts? Would rather not look like a goose when I go into the dealer to order some spares. Thanks all!
