Since my last post, I have mainly been kept busy doing odd jobs to help pay for the truck, but I did work in a few things.
62Stick, good tip about reinforcing the doors before I start cutting. I have included a few pictures of the main areas of concern, and there are some more added to my shared Google photos album (now accessible through my signature, not the prettiest link, but it works. I'm still trying to become UBB literate). I also got some of the wiring and heater components stripped out of the cab
I also pulled the big truck gauge cluster from the new cab and started digging around about how I can get the tachometer work with my six cylinder. Apparently there is some kind of capacitor that can be swapped to make an 8 cylinder tach work on a six cylinder. I also confirmed that it is an external input unit, so I'll have to get the rest of the gauge off of the C-70's fender well. I was a little disappointed to find out that it is not a factory tach. It was made by Sun Electric, and it has been modified to make it fit into the factory cluster. It fits, and looks good, so I'll probably use it anyway. I noticed when I was stripping the wiring etc, out of the cab that there were 3 aftermarket gauges (temp, oil pressure, amperes. Judging by the style of them, I'd say they were installed in the 70s or 80s) that are redundant to the ones in the cluster, so I'm guessing the gauges in the cluster don't work. Hopefully I can repair them.
The main thing was that I found a Borg Warner R-10H overdrive on Craigslist in New Jersey. I picked it up on Thursday, timed it just wrong so that I was on the I-495 beltway in the middle of rush hour. It turned out when I got there that it was actually a package deal for 3 transmissions (all passenger car trannys, and only one with overdrive). The Idea is to take the overdrive off and put it on my transmission. I think I can sell the other two transmissions for close to what I paid for the lot, so that will help offset the cost of the switches, relays, etc, none of which were included. Anyway, I tore it down this morning to inspect it, it is internally in good shape EXCEPT for the planetary gears. I looks like all three shafts holding the planet gears into the cage sheared off, and one of the planet gears got pretty badly mashed up (pic attached). The sun and ring gears are still good, although the sun gear is definitely worn. I guess they must be made out of stronger material the planet gears, so the planet gears basically acted like a shear pin. I am going to post in the driveline forum about possible solutions.
