When I bought my 91 the stock stereo had a blown channel and the antenna was broken off. I ended up putting the CD player I had previously removed from my 98 into the 91. Since the 98 has the antenna built into the rear windshield it didn't support a power antenna. So I just went down to Advance and bought a manual telescoping unit for 6 bucks and it has worked fine (reception and no leaks) ever since.
