Sunroof Dart (1973) Question???

I have a 74 duster w/sunroof and good luck finding parts if you would need any. I haven't found them yet and I am kinda wishing I didnt have one right now, the factory DID NOT install the sunroofs they sent them to a company close to the assembly plants, that much I know.
Sounds like a normal MOPAR owner issue regarding parts. I've been looking for a Driver's Side fender extension for a 1967 Chrysler Town and Country Wagon for nearly 5 years. I found one but only got the shell....not the turn signal nor the lens....extra $75 for those plus shipping. Paid $100 plus shipping for the extension shell.

The 340 I'm looking at has been a challenge for me.... as it is a project...all there but rough..... and it's current owner and I are back and forth on price. He says very rare and needs a lot of money. I say Yes...maybe...neither of us can state for sure on rarity..... I think about $800 -$1000 for the project. He won't give me a price....just that it isn't enough money.....oh well. Sounds like maybe I should just walk away and remember to enjoy the chase. Thanks for your post.
