I don't think the 241 case ever had a th350 in front of it. I am not sure of the spline count on the 208 case with a TH350, but a 241 is dimensionally identical to the 208 (as far as I know). The driveshafts, shifter linkage, and crossmember should be a direct swap. If it was me, get a 4wd 700/4L60 output shaft, put it in your existing 2wd 4L60E trans, and run a 241 case.
