Hi gents, thank you for the replies, it’s what I feared tbh. I am thinking I will look at modifying the tunnel and because of the structure aspects I will have additional strengthening added, I put both descriptions into the thread incase like mentioned it is a similar issue to both models, measuring it the offset is around 30mm the required mod only needs 20mm at the top to allow for the seat sides, the base of the seats has more than enough room, so in thinking a diagonal cut and replace the tunnel too that is currently tacked in place with a bespoke seam welded tunnel top will solve the structural worries. You know that feeling when you think that’s a good idea then you start and realise, umm a few additional hours may be required lol. Mine is the mk3a, has either of you or know anyone who has fitted a floor mounted pedal box? Ta Paul
