so i just got a 79 d50 with a 2.6l but its missing some emission parts. unfortunately i live in cali where i have to smog and the only thing im really missing is the heat riser that sits on the exhaust manifold and goes to the back of the air cleaner. havent been to lucky at the junkyards and when i do find a truck its usually efi models of is just gutted completely. anyone know of a website or may have what i need? thanks and forgive me im new lol
