Re: Need easy answers fast-1983 3/4T
Yup, 14 Bolts on the Diff cover. If it's an old guy who's had it since it's new, you could be lucky, and it could be in excellent condition. Mine is because my dad is an awesome guy with maintaining his stuff. Has alot of Pride of Ownership. On the forum, Search for "Pride of Ownership" if you want to read about it, first post I ever made about my truck. We've had mine since it was brand new. So I know what came stock on it, everthing under it. Unless it's an ultra-lite 3/4 ton (which I've never heard of) it's gonna have a 14 Bolt Semi-Floater in the rear. So you probably don't have to worry about it having a 12 bolt. The Heavier 3/4 tons had the Full Floaters, especially the Camper Specials.
The 12-Bolt rear is an irritating rear axle to say when it was stopped being used. Personally I like to think of it as dead in the very early 80s, like 81-82. It was replaced with the 10 bolt in the later years. But since it was so common it found it's way under some early-mid 80s rig as leftovers. I think as front axle's go, the Dana 60 only came on 1-Tons. Maybe on 3/4T Camper Specials.
You shouldn't have any trouble at all with the 208 if you're not going any really hardcore stuff. Lots of people swear by them. The aluminum shouldn't bug you. You're not runnin huge tires, with 450+HP right?
The '77, other's will probably add more to what I have to say on it. Maybe Dana 44 in the front, possibly a 10-Bolt. I'd bet on a D-44. Same tranny, the sm465. Unless it's got an sm420, which I think was ditched in favor of the 465 alot earlier than 77. Difference is lower granny gear (7.xx vs. 6.55 in a 465), and more expensive to find parts for since it's older.
As for the wheelin you'd do, I'd say as long as your gentle with the gas, it should hold up pretty good on 35s (hopefully 4.10:1 in the rear), and be a very dependable truck. Weakest point for you will be the front axle since it's prolly a 10-bolt, but as long as you traverse your ruts gently, should hold up just fine. My dad used to load his up with 110 gal of fuel, about 600 lbs of tools, a welder/generator and full Oxy/Acet setup, and go drive around in fields (it's got a set of airbags in the rear to assist). It was our farm truck. Held up pretty damned good I think. [img]images/graemlins/cool.gif[/img]
