Hello, I am a Newbie

Yeah, sorry to see your old dart go out like that, oh well. Good to see your making the best of the situation. Looks like it had a/c at one time, you may want to put that back in, living in AZ and all. There are heater boxes w/ controllers for the 73+ floating around here for dirt cheap if your parts car doesn't have it. You might be able to find the rest of the parts on here too, or at least the key ones.
