I'd be inclined to use a short rear dogbone(MGT one may work?) and then have a long one made for the front to keep the weight distribution rearward.That's just me though,just a suggestion,alot of trucks seem to work best with a rear-mid engined type weight distribution but the downside is you will compromise turn in and on power steering,but you gain rear grip/traction.

Or go for middle for the tranny(equal length drive shafts),and have your batts able to move forward or back for adjustable weight distribution.
