Defroster vent replacement - How hard???

April 75 - Hamtramck, also. I noticed yours has buckets and dual exhaust. Did you add the duals? If so, did you add converters as well? Was it the same H- pipe and hangers as a 73-74? It looks like the same headers as the 74 dart Sport 318 I had. It's nice to see what it looks like with the Rallye wheels. Looks good! I can't quite tell the original color, but it looks like Spanish Gold??
