The 6 lug D44 was stock on the blazer and 8 lugs were optional on the 3/4 ton trucks. Somewhere in the early 80's they changed over to the corporate 10 bolt which MAY have been weaker for less splines on the axles, but I cant remember exactly what the comments were.

I have my 72 front axle w/ 3.73 gears for sale on CL. It has all new tie rod ends, ok brakes, Zero Rust and was being used till a few weeks ago. I listed it for $250 and received one email... I think it depends on the location.
