Hey guys, I need to order some spirolocks for my Probe .030+ 454 pistons, .990 Pin, and can't find a part number anywhere on the internet. I'm ordering some parts from Summit right now and don't want them to send out the package until I can get the part number for the spirolocks, any help? Or maybe a general spirolocks that work in these pistons (not sure). Summit sells some speed pro ones but they are $3.50 a piece, and I need two per side of the piston.... So 32x3.50=Ouch.
