Where? The southwest is a guaranteed home run as Philip said, but that's often not an option. Garage or barn find gassers are a fair bet too.
Price? I priced an essentially rust free loaded cab with bad doors at $300. I wanted it to sell quickly.
Some things you should know when looking for a cab/donor:
-Having a 5 speed means you have the tall floor. The floor section can be cut out and transferred to the new cab if it's not rusty.
-Check the drip rail, rockers (front and back) and the front corners of the cab. Pull up the carpet and have a look. Dodge evidently wanted these trucks to rust out ASAP.
-If you see a bubble, run like the wind
That bubble is hiding a huge mess.
