The reverse lock out on B&M doesnt work at all for all E0's (or at least most from what I know). The shifter assembly is slighty different from 98.5-00 from what I understand. But it will work perfect with the additional of one small washer. Thats all it took to make mine work. It just needs to be placed under the little metal corner piece on the shifter base. It the piece that the shifter is supposed to hit if you try to shift to reverse without lifting the lockout. For some reason, on E0's, the metal corner on the base is too low and doesnt make contact but if you place a washer under it, it works fine.
