Default Spark Plug wires

Edit - Deleted parts about the wire size. Found my earlier post about how 7mm would just be as effective and that I have a 75 distributor.

Does anyone have a trusted brand of Orange spark plug wires? I would like them to be 7mm and fitted(shorter?) for the 74(75 distributor apparently) because my current ones seem like they’re too long.


I’ve recently replaced my fuel filters and made it black with orange clamps. (In time, my Exhaust manifolds will be black as well so balance out the orange/black.

Spark plug wires were originally routed from below with the two forward wires going thru the motor mount brackets. This requires longer wires than coming from above. You can find wire sets pre-cut to come from above or below. 8mm fit in place of 7mm wires but needed larger holes in the looms holding them.
