Check your local want adds and you may g lucky by running across a truck with a blown 6.5 and a manual trans.
You'd probably have to buy the while truck, but you'd get everything you need right down to the pedal assembly and then junk what's left. Your donor truck is also a perfect road map; unbolt part from donor, reinstall in same place on your truck.
Trucks with dead 6.5's (snapped crank, cracked blocks, dead pmd, etc) go pretty cheap around these parts and can be had for around 500 bucks. Hopefully they do where you are too.
As a side bonus, you can scab some spare parts of it (ie: wiper motor, etc) before it goes to the crusher.
