ARP main stud interface with oil pump

Here's how it's gone for me several times. I call ARP and tell them of the stud clearance issue. They tell me that they have not had previous reports of a fit problem. After some pesistance I suggest that they check for a bulletin regarding the issue. They put me on hold. Then they tell me it has not been a problem for others but that they do have a special bolt that they can send me. In a few days a "special" bolt arrives and I check fit to se if the head is low enough. Usually after some minor clean up of the oil pump housing the new bolt provides a couple of thousandths of clearance. If not, I take the bolt to my belt sander to buff a few thousandths and get a fit. I hate putting in a bolt after spending money on a stud kit but on the rear cap I find no perfect solution. Seems like ARP would properly address the issue but we are only Mopar folks after all.....
