Thread Size? ARP Main Stud and Melling pump
I need to know what the thread size for ARP main studs on an LS motor is. I have to bolt up my windage tray, and the stock nuts are obviously not the right size. APR doesnt have it listed on their site. Also, anyone know what the thread size is on the Melling oil pumps for the pick up tube? I cant seem to find where I put the bag with my stock oil pump bolts. Figure I'd just pick up those when I go to Lowe's for the windage tray bolts.
