Does anybody know if they make 8mm plug wires for a 1969 383HP with manifolds.oem wires are 6 90 degree ends and 2 straight ends.I got a set of MSD wires and the ends were all straight so I returned them without seeing if they would work.Probably should have kept them because if they make an oem set I have yet to find them,any help would be apprieciated.
