different size in diameters, so top clamp size is an issue
I said it is not a STRAIGHT swap
With fiddling and other parts, you can make it work. You can make everything work, but will it be good (handling??)?
But then I think: is it worth all the trouble? Will it not cost more in the long run? It may be nice as a hobby, but if you want a quick and easy upgrade of your suspension, I would do something else (new front internals and new shock).
About the shock, I am not sure, but I think there is a little difference between 959 corse and the 1299.
If the shock fits: just get some front upgraded internals and go. I would not bother placing another Tee, ... This may start a non-ending adaptation of parts (ending up in a complete front of a 959, including wheels, brakes, ... expensive!)
