A578/T350

This category is filed under Transfer Cases with the model number A578/T350, but every product title in it reads BW1356 Remanufactured Transfer Case for Ford. Eight units are listed. Four carry the model number A578/T350 in their data and four carry A578. That is how the source data reads, so order by vendor SKU rather than by the category name.

What fits what

The titles give a year range and the make only. No vehicle model is recorded on any of these eight listings.

• 1991-1992 Ford, vendor SKU RTC1356F-1BM
• 1989-1991 Ford, vendor SKU RTC1356F-11YM
• 1989-1991 Ford, vendor SKU RTC1356F-11Y

Four separate listings cover 1989-1991 Ford, so the year range on its own will not get you the right case. Use the numbers below.
