Upgrading headset to threadless

[Andy 308]

I have an older soft tail that has served me well over the years, but I need to replace the old threaded forks. Am I able to replace with a threadless system or am I searching ebay for threaded forks?

It's all depends on the diameter of the headtube bearing seat and/or how it is seated. I would take it apart and bring it into a shop to see what the cup size is for the headtube, then you should be able to match up the ride size. I don't see it being a problem.
