OK....They are different seats (Sorry Azzurro)..
When the guy was welding the base from the original seats to the bottom of the other seats, the phone rang..... on his return, he found a weld ember slowly burning its way through the seat
So they had to go and search for another set...overall, I'm happy. Wheels have also been replaced, so will get a few pics later. I'm also sorting out a mistake I made with the arches
