The problem with using blowers for a 87-93 on a 94-95 is that the pulleys don't line up the same. The 87-93 belt is further away from the engine (ie - closer to the radiator) than it is on a 94/95. If you can figure out a way to modify the mounting bracket to move the blower closer to the motor and make the belt line up, you'd be in pretty good shape. You may have a similar problem with the discharge tube.
Other than those things, I can't think of any other reasons why it wouldn't work.
Or I wonder if the 94-95 bracket for the 2000 is compatible with the 1220?
Or another option would be to convert to 87-93 accessories ...
