Anyone know what the part number is for the rear shock stud?

Its those 2 prong things that your rear shock/coilover goes into and tightened down with a 12 mm nut..

I was installing my rear coilovers and on one side the stud got stripped. I'm now driving with 1 nut holding on my rear passenger coilover.. Need to fix this asap and can't find this part anywhere.

 

Those two prongs/studs go into those two holes on part number 6/8 in this illustration
