Default spark plug wires

Has any one know the Xact spark plug wire set manufacture GP Sorensen of quality on a HEI car 1977. Have had this set for 20 plus years and are 8mm High energy suppressed ignition cable. I assume they are correct for a 1975-1979 Corvette.

I may be preaching to the choir ... it seems GPS no longer markets sp wires

GPS is still in auto parts marketing business and is a unit or Standard Motor Products ... but no GPS wires.

There's always the possibility of NOS sp wire sets on fleabay etc but you'd need the set/part # and that's not shown in GPS eCatalog

Maybe a longstanding parts store near you would archive (stacked in a dusty box out back) obsolete countermans' catalogs.

good luck

Those wire no./lengths are all mis-identified.

Yes, OE wires for 77 HEI are 90 angle at both cap & plug

either of these sets should do well ... either under $30/set

I just installed this set. They were all a couple of inches longer than OEM which wasn't an issue.
