has arp bolts (8740)
3564 numbers on the rod (crankside)

If the rod is a Carrillo it wil have a small indentation in the center of the cap between the two forging ribs in the center of the two bolts if it does not I beleive it looks like a Manley but check for the small dimple or indentation it will look like a pen tip mark in size Good luck Laz
