I've been working on yhe doors for those truck and been trying to decide what to do with the door latches. These old 40s and 50s cars use latches like you house door. If the jam gets out of whack at all be it a harsh bump or an accident, thw doors pop open. It's also very tough to close them and the latches don't catch very well as they wear quite quickly.
The idea of figuring out how to use the latches from the 2002 S10 doors has been rolling around in my head for a year or so. I finally went out and got one of the doors from the donor truck and cut the latche from it and pulled all of the parts out of the door.
The latch is a really nice compact unit but still quickly became obvious that it wouldn't fit, or at least it couldn't make the turn around the window track to get in place. So I went back to trying to clean up the old 1949 latches.... After a while of working on them, I just couldn't do it, they are so rustic and just plain crude. No matter how much improvement I make to them, they are still horrible.
So I went back to the S10 latches.... I found that there is enough room (barly though) but they would have to be mounted from the outside. Basically cut a hole, put them in and then bolt a plate over them. I thought that was crude so I went online to see I'd someone made an upgraded latch. I found one company that does and they do it exactly as I described above.... and cost 500-600 dollars.
So for the past few weeks I have been working on building a bolt in plate and brackets, springs, rods and thing to make the original door levers operate the new s10 latches. I also created parts to make the locks function. This truck didn't have locks except on the driver/curb side. The lock also only functioned from outside. I am creating a lock handle and going to CNC them from aluminum at work too.
I have a junk door that I cut holes in it so I could measure for rods and brackets. I have the latch and locks functioning on this test door and I'm working on a mirror image of parts for the other side right now. This should be a great operating door when finally on the truck.
The red plate is what I made to bolt to the door. I did save the hardened backing plate from the s10 behind it. May not be as strong as it was in the s10 door but stronger than the latch and plates that were originally in the 49 door.
I cut the hole below the outside lever too big to install the lock. But I test fit it and it functions.
