need help on parts and airbags

[fallensoldier45]

hey guys.
i started work on my 86 2wd last weekend. she got hit and tweaked the frame. working on an lt1 conversion. i was wondering i want to get rid of the leaf springs and just run airbags on the back. anyone have ideas on how to do this. can you do a 2 link setup with a panhard bar or is it easier to just do the four link setup.
also i was wondering the best place to find interior parts like the plastic panels next to the seats where the top mount for the seatbelt is and the top rear panel of the headliner.
anyone have ideas for blacked out taillights. like where to find them or how to do them
