Offtopic: 66/67 D100 door mechanism

[tparker]

Hi All,
A bit off topic, I hope you all don't mind. I have a Dodge D100 1966 or 67. The Door latching mechanism is worn and are VERY expensive to replace with one that may not be in any better shape. There is a wheel that is worn and apparently it can be flipped over and the unworn side can be used. Disassembly is fairly difficult and I ended up just cutting the cover and will weld it back together.

The problem is I will need to deal with the pin that holds the wheel in place. I have no idea what type of pin it is to see if I can replace it or if I will need to use something more modern like a pin with a c clip. It appears to bbe like a rivet where one side has the rounded head and the other side is mashed over. Anyone have any thoughts?

The photos are a little hard to tell, but the bolt is on the round housing just below the red and yellow screws. On the back side it is in the center of the pic with the 6 lines radiating from the center.

Thanks
Tom
