If you're still looking for seats, I have the two original Parker seats from my 2300. I replaced them with a leaning post. To the best of my recollection, they are pristine.
Well, I should have known better than to count on my recollection. They are not pristine but they aren't far from it.
I broke the collar that goes around the post on mine . What would you need for them? Of course assuming the op has no interest or is not what he needs.
To mthomas, I assume you mean the adjuster, what I would call the adjuster anyway. I don't have those. As far as how much I need for them, I'm not sure. I wasn't looking to sell them, in fact I forgot I had them until I saw this post. Why don't you make me an offer?
