If it were me, I'd go with an adapter from advance adapters and a Dana 300. The aftermarket is huge, it's a small lightweight case and with a remote shifter it should make it alot easier to keep a stock look in the truck, you could even run twin sticks, plus it's a stronger case. The 241 doesn't have as much support, and I'm not sure if they make a remote shifter but isn't the 241 a straight pattern shifter (forward and back movements for all gears)? That would make it a little harder to fit in the VX console. Here's a pic of a guy who swapped in a 700R4 (same basic trans as your new one) and running a Dana 300 with twin stick shifters in a Passport (Rodeo, same basic console lay-out as the VX):





he had to push the trans towards the drivers side a hair to clear the torsion bars with the tcase but since your doing a whole motor swap, this shouldn't be much of an issue, and his fix was easy and worked.
