Factory Suburban stuff (71 & 72)

[The Blue Pig]

Hey guys, it's been a long, long time since I've perused the forums. Anyhoo, I found a guy locally that has a 72 Suburban for sale. He said it goes through oil, is kinda beat up and rusty, needs a mirror, wiper motor, etc. It's got a wothless, tired old 307, a turbo 350 and needs some "tlc". Anyhoo, it's the 3 door with the two part ...tailgate...? style rear doors. He wants $400 dollars for it. I have been scouring the forums here and havent come across a solid answer to a couple questions I forgot to ask him. Of course, it's basic everything. Manual steering and brakes, no a/c, blah blah blah. First off, I am not really looking for a show truck, more something to put a decent engine in and putz around, maybe tow once in a while. Did they switch the half tons over to 5 lug with disc fronts in 71 like the pickups? What are your varying opinions on whether I should pick this old bone up or not? Thanks for lookin!
