Thanks for the responses so far! If you have any further leads (or have these parts around), please let me know!
moparclown: Thanks for the tip - I found those parking lights on the 'other site'...I will follow up if nobody around here has them.
CP: Do you know what you would want for the markers, considering they have to ship from beautiful AB down here to Michigan?
Dave: Thanks for the links. I've bought stuff from you before, including those beautiful tail light housings a few weeks ago!
dodj: If nobody has any '70 hinges, I will be sending you a message soon.
Thanks again, and please keep me informed if you have (or know where to get) any of this!
