New Member Just Bought My 1st Mopar

Welcome to FABO! You'll like it here.
Suggest you look for a couple of things on eBay:
* Motor's Manual that covers the year of your car. I always liked the Motor's Manuals better than either Chilton or Haynes.
* Factory Service Manual on disc. I have the '69 Service Manual on disc - dont' know if they have the '73 model year on disc.
