the output spline on a 241dhd and a 263/261 from a duramax truck are the same. I just put a 12v with a nv4500 and 241dhd in a 95 chevy and we used the stock slip yoke and driveshaft out of my 01 puller. the 1410 slip yoke from the dodge is even the same part # stamped on the yoke as the chevy. the front driveshaft wouldn't be that hard, we haven't made the driveshaft yet, but it appears the ujoints are the same size.
