Advance Adapters offered a conversion kit to mount a T5 manual transmission to your stock 2.9-Liter V-6. The kit used an adapter plate that went between the T-5 transmission and your 2.9-Liter bellhousing and used an internal release bearing (Ford# F1TZ7A-564A). Bellhousing modifications were required.
