These are Taylor Spiro-Pro universals - and with a full MSD ignition are operating just fine. It takes a couple of hours to make up the wires, but for sure a lot better looking then the "custom fit".
My tools - a box cutter knife, a crimping tool and some silicone dielectric grease to get the boots on at the distributor end.
(I do like the tool that Malc pictured !!)
