Single ballast resistor

Looking for a clean single ballast resistor for my 1970 dart. I am wanting to solder it across the back since I have an HEI ignition. So a nice but non functional resistor is fine. The aftermarket ones I've tried to get are solid in the back and can't be easily modified.

Thats what I did with mine after th HEI conversion. My thought was it would be cool to still have it on the car and it is.

Edited this in. The power from the ballast resistor actually operates a relay. The relay sends the power to ign.
