I had both the 90 and the 94 4x torn down at the same time and the floor was the same in the 90 just lacking the extra hole for the transfer case. Id suggest getting a 2x and finding a W-56 of buying one from Marlin fot he truck. You'll be much happier with that trans Im sure. The frame's are of equal strength Im sure, Ive beaten the shizzle out of my truck and had nary an issue with the frame.
