Upper Control Arms

[boot_smart]

Hi all very nice site read lots of stuff here and gotten alot of good information. I have a problem that I cant seem to find a anwser to anywhere. Im in need of new Upper Control Arm Bolts with the splines on it. These are to keep the bolt from rolling as they have a rivet type head on it. They carrie 2 types of washer with them, a thick one with a convext type curb on one side, flat on the other. The other washer has a thinner cone type side and flat on the other. Ive check the dealers from just about every fastner and auto dealer from atlanta to chicago with no luck. Any help would be very much apreciated. Thanks
