You'll have to change the driveshaft yoke to the finer output spline of the 350 or an M-20 or M-21 yoke will work, but the driveshaft or crossmember won't have to be changed. Check the bolt pattern on the flexplate and be sure the 350 converter will bolt up, if not you'll need a 350 flexplate. Also, check the bolt hole alignment on your starter of you have to change flexplates--the straight pattern was for the smaller flexplate, the staggered pattern was for the larger 168-tooth flexplate. Pretty simple swap. I'd check with the repro companies about the console parts--the Turbo 400 stuff may be being reproduced now and will work. All in all, this is a fantastic swap to get rid of that "Slip-O-Matic". Low-end response is unbelievable compared to a Powerglide. Good luck.
