I really need a new or used air damn/ground effect for a 1988 chrysler conquest or a 1988 mitsubishi. please let me know?

Previous owner had no idea either I always assumed it was a 12a but after meeting up with another member there was some doubts. I tried to look for some pics of a 12a on here to compare without making a thread but the search bar comes up with no results. http://i.imgur.com/YUgTN.jpg http://i.imgur.com/pSE1g.jpg http://i.imgur.com/PfYqU.jpg

As topic states, where would I get replacement parts?

A kid, I'd say 18 or so, said he used to have a Starion and wanted to know if I'd sell mine. I said I'd need at least $6k and he was like "is that all?!" I have a decent amount of work and some kind of rare parts but don't think I could get that from someone here. I love my car but it has never work 100% and is a constant source of disappointment as it always leave me stranded regaurdless of how much time and money I put in. Fix one thing and two go bad, I am getting frustrated big time. Regardl
