Advance Adapters
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. This kit should only be used for a 2.9-Liter engine.
Part No. 27-1001 – T4 transmission to Ford 2.9-Liter with overall length of 26-3/4 inches
Part No. 27-1002 – T4 transmission to Ford 2.9-Liter with overall length of 28-1/2 inches
Part No. 20-0021 – 5th Gear upgrade (17% Overdrive)
Update:
I no longer see the (3) part numbers above listed on their website. Here is what they say about the T5:

Advance Adapters no longer offers kits to adapt a manual to a Ranger transmission. Contact Advance Adapters for more information 800-350-2223
Modern Driveline (MDL)
Modern Driveline offers the Quick Time Bellhousing, Ford 4.0L V6 to Ford T5/TKO/TKX SKU: MD-401-4060 to mount a Ford T-5 Manual to a Ford 4.0L engine. From the look of the bolt holes, this looks like it might bolt to both the 4.0 OHV and 4.0 SOHC. If it were to only bolt to one, it’s probably the 4.0 SOHC, but this looks like the same bolt pattern as the 5R55E automatic which will bolt to both an OHV and SOHC engine.
