I don't have the frame yet so don't know how long I need - gut feel is it should be long enough. I do know I need 1 and 1/8 inch thread less and plan to run v brakes.
If you think yours would do the job are you happy to sell? And does it work etc?
Not sure how well or if it works. I know its orig and never been apart. If there is rubber bumpers I am sure they would need to be replaced. I will check the travel and rebound and measure and report back.
