2wdblazer- That's what I thought too. They were made from somethink like 1.5" tubing.
By the way, I noticed on Blazerworld.net that there is a Blazer for sale in Florida. I thought of you because I know you were looking for so long without a single 4wd for sale down that way. I think you got a better deal from the description of this one:
1970 k5 blazer for sale: 307 V8, 67,000 miles on engine. Tranny rebuilt less than 1,000 miles ago. Axle has been swapped from a D44 to corp.10 bolt in order to have power disc brakes. I will include the old D44 in sale. Corbeau seats, 4" skyjacker lift, 33" BFG M/T's, many more goodies. The all important rocker panels and cab supports have been repaired!!!! I am asking 5,000. If interested feel free to email me with any questions at
