. I am using the HR7500 on my Challenger and it has done well for over two years now. I was careful to use the coil they recommend. You can buy the HR7500 from JEGS. On my Charger I am using the FBO box and REALLY like it. Only been a couple of months but I am impressed. Again, I used their recommended coil and by-passed the ballast, and am using a Voltage Regulator with modern internals. For the FBO I bypassed the ballast by taking out the resistor from the back and substituting an 8 gage wire, using the same connectors, then I potted the back…so looks stock.
