Moog part number for chevelle pittman arm?

[charcoal01]

Was hoping maybe one of you guys could help me out, need a Pittman arm for a sweet 12:1 box on a 68-72 chevelle. Centerlink side measures a little over 5/8 on the bottom side of the hole. Ive asked all the local parts stores and they all tell me it's not available, maybe there is a newer car that uses the same arm? I have one coming from speedway but was hoping to find one locally. thanks for the help

Pretty sure they only came off of the power steering 68-72 chevelles and maybe the older ones.Southwest speed has them. They are a non wear item so you wont find them at a parts store. Only place locally would be a junk yard or a chevelle guy.
