I have a question about a truck I found for cheap. I have an 89 K5 I just lifted and put 36's on. I've been looking for a donor vehicle to buy so I can steal the parts off of. Well, I found a 1979 GMC Sierra Grande. I know it's got a 400 small block and a 12 bolt rearend, but other than that I couldn't tell in the dark when I looked at it. I was wondering if this vehicle most likely had a Dana 44 front or not and if it came with a 205 T-case. Any idea of gears? The owner said that he thought the t-case was some kind of special t-case that GM made in which you could hook up a pto winch, but I've never heard of it. Is this the GMC version of a camper special? The stickers on the glove box and doors are gone or beyond clarity. The guy only what's 400 bucks for the truck, but I just want to know if it's worth driving 45 minutes away to inspect any further.
