Any parts to get my Cuda good gas mileage (other part listed)

Pertronix is nice, but you can scrounge a factory electronic control unit and wiring harness out of anything post '73 in a junkyard and buy a slant six distributor for an Aspolaré for way cheaper. Also, you should be getting 20+ to the gallon out of a stock slant in a car that light. There's absolutely no reason why you shouldn't drive your car anywhere you want. It's a car.. All I own is old rusty junk, and I'll drive any of them anywhere. Safety? More important than worrying about what your car will do in a crash, is maintaining your brakes, tires, and suspension so that you can avoid a crash. Flush your brake fluid once a year, and if you're running stock 9" drums, you can consider upgrading to disc.. The Kelsey Hayes setup is the easiest to install on your car instead of the later big bolt pattern stuff. If you're happy with your drums, or poor like me, there's modifications you can do to your drum brakes to better vent them and keep them cooler. PM me for info
