2wd and 4wd have different mounting locations for the gear box. The gear box is the same between the two, just mounted in different postitions.
When you do a crossover steering conversion, you move the gear box to the 2wd position, which is higher on the frame which make the shaft shorter.
I had a borgeson on an 80 trialduster. Put it on an 88 RC, but it was too long, so I cut it down. Went to put it on my 84 RC, but it was too short. I did the crossover steering conversion on the 84, and now the shaft fits perfect.
So I am not sure if the later model RC's came with the box already mounted in the 2x position or not, but it seems to be that way, since my 88 needed a short shaft that works exaclty the same when the box is mounted in the 2x position on my 84.
Best thing to do is give them your measurements from box to rag joint, or just measure your existing steering shaft end to end.
