Read my earlier post about the great MP American comp.The SS spring hangers are wrong even though they say 65 B body.They are an inch too long on the holes.Then they cant even get the studs drilled in the proper spacing.They have been like that for years and dont care.At least if Source has a problem they try to fix it.Oh and ask John has ever bought anything from them?Oh and lets not forget Eddy with their intakes that the bolt holes dont line up with the heads.Im not talking about a head that has been cut either.I had to open the holes on the last 3 Intakes that I installed from them.Rocky
