1996 JEEP CHEROKEE User Comment / Complaint

I have three rhd jeep cherokees and they are for us postal delivery. 1994, 1995-, and 996. i have called jeep & chrysler corporation asking them if my vehicles are fmvss certified ,and they refused to answer me. they said i need to be a senator or a congressman to ask that question?? i asked for right hand drive crash test information, and they hung up the phone. i e-mailed them, and was told this was a corporate issue and rhd jeeps for didn't need to meet safety regulations?. i talked to the dot, and they stated they didn't know of any rhd vehicles built and sold in the usa. was this some kind of joke? the dot didn'tt know? one woman at dot asked me what side of the road do we drive on in usa? the epa knew about them, but for safety information i was told to go back to dot. can somebody tell me what was going on.
