33 1/4" is what I came up for a measurement on this PF center to center on on the U-Joints. I still haven't made it to the dealership to see if the piece that slips into the Frontier transmissions is aluminum as well. Sweet if we could all have aluminum and now I'm wondering why every other Nissan 4x4 truck comes an aluminum DS other than the PF 4x4.
If there are any machinists here, how hard would it be to take a longer Frontier aluminum driveshaft, cut it to PF size, reweld it, get it balanced and save another small additional amount in fuel economy.
