Yes toss the 5R110 sell all the 6.8l and 5R110 parts. You can find 12v's in all kinds of vehicles but your best bet is to get one from a Dodge truck, there is a lot of small pricey parts to convert it from a med duty motor to light duty I found out the hard way, but I got a smoking deal on my motor. Do not rule out the dodge transmission a fully built 47rh/re is not a bad transmission. It will save you almost $2000 in adapter plate and PCS. Money that could be spent on building the transmission. The 47rh would be the ideal way as it is hydrolic but add a manual shift kit to the 47re and you are in business. As for transfer case you can keep the NP473 and just change out the input shaft to fit the dodge tranny's output shaft, they will bolt together but the front drive shaft of the Tcase will be lower than stock so there might be some cross member mods needed. I did not have to cut or lengthen either drive shaft but I did have to make a mounting plate to mount the tranny to the cross member.
If you go standard the dodge NV's are good but parts are getting hard to find but you will not need an adaptor plate but you will need to get the hydrolics (master/slave cylinders) worked out. The Ford 5 speed and 6 speed either will work you will not gain any MPG's from the 6 speed the extra gear is a low granny gear if you are pulling @ssholes out of elephants than thats the one you want but for MPG's it wont matter so look for the best deal.
If you are just looking for better fuel milage I have heard of a guy that put a 4bt into a 04 crewcab 4x4 SD and is getting mid 20's. He even says he can pull an 8000-10000lb trailer with it.
So an Isuzu diesel might work as well. Food for thought.
