I put an aluminum center section in but the studs are not long enough to put washers on them with the nylon locking nuts that I have. summit has these from arp http://www.summitracing.com/parts/arp-250-3005/overview/ but they say its for a ford are mopar the same studs. Specifications for arp OAL 1.645˝ Thread Size 3/8-24 Pieces 10 nuts, washers included

EDIT Sounds like you are wanting to protect the alum, you otta be able to get a real real thin metal washer (shim) to take care of that & still give you enough thread engagement (any more than flush is a waste) Last edited by RapidRobert; 04/17/14 12:00 AM. live every 24 hour block of time like it's your last day on earth
