I don't have the 69, but I'm building the 71 as a 4x4 (look under "noise stroke"). The frames look very similar between the 69 and 71 from what I have seen other than length. Mine is not stock, but if you were wanting to build a stock 1/2 ton 4x4 the 78/79 kit could be a donor for axles and transfer case, or you could simply get resin parts from someone like B-N-L. If I were going to make a stock 1/2 ton, I would recommend using real coil sprigs as opposed to the cast ones. It will give it a more realistic look. You could make coil spring mounts out of styrene. The original rear springs could probably be used with a 3" scale block. Depending on how accurate you are wanting to be, the front cross member is slightly different between the 2 and 4 wheel drive, and I don't remember the detail of the 78/79 kit, but on the 1:1 the steering was slightly different on the 77 and earlier models. However, if you are wanting to make a lifted version, the sky is the limit. On many of the 1:1s that were 77 and earlier models, the original parts (steering, radius arm mounts, shock mounts, etc.) were replaced with 78/79 parts on lifted vehicles because they were better and worked better with lift components suck as radius arm blocks. I like these models in 4x4. I'm looking forward to seeing what you put together. Hope this helps some...Brian
