I missed a few posts. was some one asking about thread sizes on JT frames. I have coffee jars full of bolts that came from Ken & Norman's. the nuts were brazed on as fittings.
you can get these from me for the cost of the post.
incidently, it was Ken's wife Honor who drank the coffee. seemed to me like there was 50 years worth of coffee jars stacked up on shelves in Kens garage when I saw it!
