Hey, Luke.
I can definitely look into this for you. There are a few questions that I have before I can start looking into this for you.
What is the year of the 3500?
When was the cover purchased?
Do you have a RetraxPRO XR or a RetraxONE XR cover?
Once I know this information I can get the information you need!

Hey Luke, were you able to gather the details about your 3500 and which Retrax XR cover you have? Once you had that info, did you find rails that fit your 2500’s standard bed? Knowing what worked could help others making a similar switch.
