Thanks for the replies! It has the 292-6. The original GM hubs got to where they wouldn't work, so I had our local shade-tree fix-it man replace them about 5yrs ago. He couldn't find exact fit, so put some Warn hubs on that he said didn't fit quite right but "work sort-of". They don't engage the splines all the way, but the 4x4 does work. So i need to get them off of there and replaced with correct, esp if i'm going to plow snow.
