Sorry if this is not the right section but thinking fellow race buddies might be more likely to help. Looking to flow test some MP alum Hemi heads but don't have any 5/16" locks/retainers in the shop and hate to buy a set just for this. Anyone have a pair of retainers and locks they could spare? I could send them back or donate a few bucks. Some old used junk would suffice.

Thanks guys,
Chad
