Are there differences in the years 90 to 95 for these items. Would the master cylinder and booster for a Taurus with 4 wheel disc brakes and ABS be the same as the SHO? How about automatic and standard transmission SHOs? I was sure they would all be alike for all the years until I started looking into it, and I notice a lot of choice and some puzzling descriptions. Looking for a little clarity on this topic.
