Progress! Rear door hinge pin?

[Whyhike]

Progress....Body work about done so I can get some paint on the burb before the summer is out. Two quick questions.
1. Does anyone know where to get new rear door hinge pins. I found the rubber seals for hinges but H&H did not have and pins. now seeing them in in catolog I have. Any Ideas? Cut one down to shorter lengeth for a front door one?
2. On the 3rd pic there is a place for a 3rd windsheild wiper, or so it looks. Does all burbs have 3 spots or what. I redid a truck years back and did not remember seeing it look like this.

Thanks
