5spd that was bolted to my 4.0, they are suppose to be able to work from what I have read online, also wiring does not look to be to big an issue, i woulod like to run fuel cell but trying to keep cost down as much as possible for now, so may run the explorer tank side ways behind cab on my custom bed and just enclose it in, that way i can reuse all wiring going to its fuel pump and so on, same with fuel lines hopefully.
