RS Judy experts - can you help?

[Thias]

I have a strong feeling this shouldn't be a problem. I switched the internals of various judys between 99 and 95 without too much hassle. The only problems I had was that the very early Judys had a smaller bore for the lower bolts in the casting.

Maybe this article I wrote is of help for you?
