No, I didn't get their rear bearing retainer/support. The rear output of my 205 is stock 32 spline just with an ORD flange on the rear. The front output is an ORD 32 spline upgrade with one of their flanges on it too (my 205 was originally a 10 spline front output, so decided to upgrade that now while I was doing everything). I'm going to make my own mount for the rear that supports the rear output and works with my current cross-member I built and already is in the truck. You tell NWF what trans you are going to put it behind and he makes the "input" for the titan box to match (you can see it sticking out in the first pic I posted). Mine is going behind my 700r4 so that is 27 spline. The 34 spline mainshaft actually replaces the whole input of the 205. This is what makes the Titan box stronger than the eco/black box. It's the fact that there is no "intermediate" shaft to connect the black box output to the 205 input. In the titan box, its all one unit (very similar to ORD's magnum box). So you replace the entire input of the 205 with their 34 spline unit, and then the back half of the titan box bolts onto the front of the 205. Then you bolt the front half of the Titan box to itself (it splits in two...I've actually heard that the front half of a normal black box and the Titan box are identical, its the rear half where the difference is).
So the only thing in my entire driveline that will not be 32 spline or larger will be the output of my trans which is 27 spline...but luckily I have a tired bone stock TBI350 not putting put much power, and I don't beat on my rig too hard for no reason, so I'm not too worried about it. My brother has a healthy TBI383 with a 700r4, doubler, rockwells, and 47's and his tranny has held up just fine...he's even broke Rockwell shafts before his tranny output let go...so I think it will be good!
