Didn't want to put this in the Jeep steering shaft mod thread, but there is where this thread has originated. I had done the Jeep steering mod on my '89 Cheyenne but had reservations on its' retention of the steering column. When I posed that on that thread, Mr. Schurkey eloquently stated that the whole idea wasn't a good one ("Nucking Futs"). This gave me pause, to rethink the swap. So, using his swap with a GM shaft for a 3500 truck (GM 26015779), I was able to locate and purchase said shaft. They are readily available, BTW, but not through GM. Anyways, they do fit a 2wd truck, even though, when compressed, they are about an inch longer. Also, after comparing the two shafts, both upper halves (original and 26015779) share the same shaft dimensions, with the exception of length (the original is about 3" shorter). The new shaft still has to be extended for attachment, so there is still a collapse feature. Here's a couple of pics
