Here is a long shot if you are up to it. There are prolly both of those cars at Cophers or something around here.
Go attempt this shinanigan there and see if it works, if not, oh well it's a junk yard. You wont have to try this on your car, so no harm done, and you only wasted a couple of hours and a dollar to get in.
But that's just my opinion, I could be wrong.
