Well, I purchased new spark plug wire for a 58 corvette and thought this would be an easy change ,,,BUT,,,,when I looked in replacing each wire, I couldn't figure out how to get the wires out of the plug wire guides.How do you open these guides to release the wires? It looks like I have to break them apart to get the 4 wires out from either side. What am I missing here????? As special tool?

There should be a cut/slit on one side, so the wires can snake out of their holes.

You're referring to the 4 hole guides that keep the wires nice and neat for routing, correct?

Bomba_MC

That's correct..the guides for the wires ,,,but there doesn't appear to be a slit.....or am I just not seeing it. I looks like if I try to pry them apart they will just break open.

Does it look like this?

The rubber wire holders slide out of the metal brackets (assuming stock GM setup) - once out each wire hole is slit on one side to allow removal.

Good point

I assumed he already had them out of the metal holders.

Bomba_MC

They are still in the metal holders. So this rubber piece just slides out of the bracket??? then the slits are exposed?

You got it!

Also look closely at the grommet. On C2's they are marked with which plug wire goes in which hole to minimize crossfire. Just little numbers molded into the grommet. 1,3,5,7 on one side and 2,4,6,8 on the other.

Since Zip lists these as 56-82 they must be on C1's as well. Same 4 hole grommet

C1 rubber wire looms have the same numbering scheme. The OP will need to make sure he had the oil pan wire clips and the final two clips on the engine for the two most forward plug wires on each side. These other clips keep the wires from dangling down into other parts or possibly getting burnt on the exhaust. If he went with the carbon core wires he also needs to be careful handling them....they are somewhat fragile... Dielectric grease in the plug boots is mandatory but try to keep it off the plug tip.
