Those rods won't work on a 5.9 with the straight cap arrangement they have. You have to have the bigger bore of the 6.7 to get them down the cylinder.
I have a set of Monster pump Mike standard length billet connecting rods with 1/2 fasteners for 5.9/6.7. They are used and in great shape build changed. $2100.00 OBO 920-723-6203 thanks Sean
