My Blazer originally had a gov-lock differential, until it blew up and took the housing with it. I replaced it with an open 12 bolt, but I'd like to upgrade it. I'd like to keep the cost down. I don't do much offroad driving, but I do drive in the snow. My Blazer has a warmed-up L31 Vortec and TH350 transmission. The gear ratio is 3.73:1 and I'm running 33x12.5 BFG All-terrain tires.
I'm leaning toward the Yukon Gear YDGGM12T-4-30-1.
Your advice is appreciated.

My '71 GMC Jimmy K/1500 originally came with the RPO G80 Eaton PosiTraction. I don't know the p/n. They are rebuildable, and should fit your carrier.
My drivetrain is: V8 350/SM465/NP205/12 Bolt 3.73 Posi and 33x12.50x15 tires.
[No limited slip in the front end D44.]
