do you kneed overdrive wen the truck is in 4x4
or just on the highway?.
If just on highway then use SM465 to NP205 and then add one of the numerouis overdrives avilible on the back.
you could also get on good terms with a good machinest and he could make trhe neccesry parts to hook t5 to np205
also sombody makes a kit to use the np203 trany gear box backwards on the front of np205 wich gives you a huge overdrive
