Windage Tray and Main Bearing Cap Fasteners
If you buy the studs from ARP, call them and mention the studs interfere with the pump and ask if they have a bolt to replace that one stud. They will send you the right bolt. Worked for me.
Both Milodon and ARP have sets of studs with 4 of them designed for a windage tray if you want to use one. Milodon also sells just the 4 studs that will work for a windage tray.
