Yes, that does work a bit better than the "Google" search off to the side. I found a couple threads that were similar enough to answer a few questions. Looks like the Chassis Engineering mounts that go on the frame (no crossmember) should work well, and I will probably remove the existing bellhousing crossmember and run one at the trans tailshaft instead.
I suppose the other question, before I talk myself totally out of the I6, is what honest performance could I expect from a reasonably built 235? Could I run the truck at 65/70 mph with a small trailer or an honest half-ton of payload? I get discouraged when I see sub-125hp numbers on built 235's. I just feel like I'll be disappointed dropping a couple grand into a nice 235 and wishing I had the performance of even a $500 junkyard 350...
