1998 Ford Ranger rear glass, is it possible to replace it with a Mazda rear glass? If so, which B series? Thanks for your help.

 

Yes but there are conditions

Engine size doesn't matter so any B-series, but the YEAR matters and YOUR model matters

1993 to 1997 REGULAR Cabs used a gasket to hold in the rear window so are interchangeable only within those years

1998 and up REGULAR Cab used bolt in rear windows

1993 and up EXTENDED Cab used bolt in windows

ALL bolt in windows are interchangeable including Slider rear windows

So your 1998 will have a bolt in rear window, regular or extended cab wouldn't matter, so...........................

You can used the rear window from a 1993 and up extended cab, OR 1998 and up Regular cab, Ranger or Mazda B-series, you can NOT used a 1993-1997 regular cab rear window
