I'd say it could come down to the testers mood colm, unfortunately my Fabricage is such a good fit there's no space for the belts at all, but there's a harness bar in the rear section to wrap the harnesses around. I found 2 E marked harnesses in the uk for sale just finding out a bit more detail at the minute.
I've heard that before myself its very fair to be honest, i'll just give it a go and see what they say.
i'll just be giving it a go anyways peter, seems that there's nothing 100% nothing clear on the matter so i'll just have to wait and see
