This is a set of Davey & Co 1589/GM/MCN pintles & gudgeons that I bought from the chandlery in Port Townsend. I never used them. The internal measurement is 2 1/8". They use #8 hardware but it is not included.
I paid $230 plus tax, which is still a good discount off list price. I will sell for $220. Please contact me if you are interested. See the Craigslist post if you don't have my personal contact info or for pictures.
