Very clean condition seats mate! never fitted them so I don't know, but I know EP3 seats are a very common choice too. I would assume similar fitment? but I'm not sure on FN2
As a fabricator by trade, I would suggest making some brackets/adaptors rather than bending/cutting the rails.
Not only from an integral point of view but also from a sales point, you can then sell the seats on with no issues.
Brackets wont be hard to make for that as as long as you make them from study material you'll be fine, as you will be with bolts securing the two parts
Sweet cheers for that mate. Yeah i just made brackets 3mm steel bent them to shape. Its absolutely solid doesn't move at all just got to fix the rears down.
