I made a little bit of progress today, so I thought I would post a quick update. Thanks stick for pointing out that I could use that gauge cluster in my truck. That hadn't occurred to me. I was thinking about the tachometer, there was a black box (excuse the lack of technical language :)) in the engine compartment that was wired to the tach, I assume this was the actual "gauge" and the needle in the dash is just a readout. Would it be possible to get one of those black boxes from another truck, maybe a 67-72 model, they could be optioned with tachs I believe, or a big truck from my era that had a tach and a 292? I haven't done any research on it yet, so I'm just throwing ideas around.
I brought the a arms, springs and trailing arms to my house, and picked up a quart of POR-15. I wire wheeled them today, tomorrow I plan on cleaning them with TSP and putting on a coat of the POR. This will be sort of a practice round before I do the frame. I also started making the patches for the cab mounts. I'll try to post another update tomorrow to say how it goes.
