I haven't put one in the truck yet but have been running one in my 60' MGA for about 5 years now. I even bought an extra and extra coil as a back up. I haven't had any need for the spares. The hotter coil allowed me to increase the plug gap some and it made it run like a top. I have been very happy with the choice and will put one in the 235 when I get that far down the line.
