Mopar Performance Wires...Too Short

I bought a set of Mopar Performance restoration wires from Summit... set # 9797 for the 340 small block.

The wires won't fit, no matter how you divide them up.... one is always too short........The only difference from stock here is the Mopar Performance valve covers.........they are apparently just barely too high to balance these wires out properly........

Does anyone know where I can buy singles of these orange Mopar wires? They're the 7 mm from Mopar Performance, #9797's, in orange........need one about 25 to 26 inches or so..............

HELP.................. Doc
