67 dodge camper special questions

Just bought this very clean Camper Special , has 61,000 miles with a 727Torqflight and 383 . Will need a few parts and planning on upgrading the engine a little bit . I need a few interior pieces ( carpet , door seals and a windshield seal ) . Would like to put headers and new carb and manifold and maybe electronic ignition . If any one knows of a supplier for parts on these trucks let me know .
