Tom..... ...what is it you don't understand? The el-cheapo frontmount 12v conversion uses the OEM 6v coil (no extra cost) plus the mandatory "infamous ballast resistor" (no extra cost) and ADDS a 12v-to-6v converting resistor such as 8NE-10306 $4.50 (cheap) in series between the ignition switch and the infamous ballast resistor. Is that hard to understand? The el-cheapo frontmount 12v conversion using the OEM 6v coil (no extra cost) and just the Chrysler dual-resistor $7? with NO "infamous ballast resistor". Is that hard to understand? Or is this concept that "Other converters use a modern 12v squarecan ignition coil with the infamous ballast resistor. This is the best way but most expensive way to convert to 12volts." And that the cost of the modern 12v squarecan ignition coil $27 to $35 is hard to understand? As I previously re-explained, even the modern 12v squarecan ignition coil needs some sort of current limiting resistance because the 12v coil was miss-designed for just 12.6 volts and most 12v alternators output about 14.7 volts which FRIES even the modern 12v squarecan ignition coil. You can continue to use the "infamous ballast resistor" (no extra cost) which will protect the 12v coil but cause lower sparkies. ...or... you can use my secret trick 1/2-ohm current limiting resistor made from 2 1-ohm 10-watt resistors in parallel. ($1.79 from RadioShack) Is that what you don't understand?..... ...perfesser Dell
