Re-tread Mopar owner!

I just purchased a 65 Plymouth Valiant Convertible Signet this past Saturday! It's in pretty good shape for 55 years old but I will want to make improvements (that's where ya'll come in). It has a 273 v8 paired to a Torque flite automatic floor shift transmission. I'm gonna have my mechanic go through it for immediate concerns but, living in San Antonio,Texas, vintage air will be the first big upgrade. Suggestions and input are very welcome!received_926696414473648 (1).jpeg
