Mine have the carriage bolt.
I’ll measure the front leafs when I get home.
So yes I can reuse my side plates but also one had started to spread not sure why,
maybe the carriage bolt loosened.
So all 50 year front pins were the same. I didn’t see a spacer on the rear so I’m assuming the rears are 2.5.

Thanks 🎩
