I've got some FN2 tyre r seats that i'm trying to get to fit in my DC5. I went for these as I read that you can get them to fit with simple modifications and you need to bolt the DC5 rails on the FN2 seats. I have got the DC5 seats and rails off that was easy enough. However looking at the FN2 seats I can't see any way to take the rails off, is anyone able to shed some light on what I need to do to get the rails off and the new ones to fit?
