    Plug wires

    Hello....

    I'm waiting on some service manuals I've ordered here through NCRS, but I'd thought I'd ask question about plug wires for a '75 CHB Vette. What is the correct size 7mm or 8mm? I know the plugs are R44TX.

    Thanks in advance!

          I tried lookin' for a correctly dated set of these on a few sites like Paragon and couldn't find a set. Did they date-code these in '75? If so, does anyone know where I can pick up a set? My car was one of the last ones built that year. The motor is dated 07/18/75. I'm thinkin' I need a 3Q set right?

          Thanks!

            Looks like GM still makes a set...actually two sets a 608T and 9088S. I'll have to see which one works.

              Yes they were dated, you likely need 2Q75 for a July car, but I don't know of any reproduction source for this item.

                Thanks for the help, Bill. Looks like I'll just get a compatible set from GM.
