..i am in doing my arrmy reserve training here in the s.cal. high desert..so i got to thinking about things to fix....lets see spark plug wires..only can use 7 mm wires..or 7.5 mm wires..sometimes hard to get.. so i went and bought a vw rabbit dizzy cap..and with a dreamel tool enlarged the towers to accept 8 mm wires, and they also now will take 8.5 mm wires...now i have more og a selection to get when i get back..like ,taylor wires..
