I have a toybox installed behind a H55F. Mudrak bolted the H55F and toybox together for me. I still am working out the transfer case linkage and cross member for the front driveshaft but am driving it. I can post up pictures when I finalize the transfer case linkage. I cut a hole for the toybox shifter but am thinking I will still have room to mount the tuffy console behind it but will found out.
So the shaft exists
