What do you need it to do for you, under what conditions, for how long/far?
How much are you willing to spend on it?
How much are you willing to DIY, and/or have done for you by machine shops, etc?
How far are you willing to go in modifying, altering, drilling, cutting, etc., the vehicle to get it to work with the conversion?
Those are all things you'll need to answer for yourself and post here before we can tell you much of anything.
