My 1970 Norton Roadster has extended forks (tubes measure 33”). I want to covert back to stock. Have the correct tubes but not sure if I can use the current spring etc.
Thanks

...Then you need to measure the spring, damper tube and damper rod lengths and post them here if you are not sure what they should be.

I think I found the problem. All components were stock except a 9” extension was added to the damper rod at the top. I removed it and now measurements are fine.
