Predicament. Polo 6R rear seats

Ok I have acquired a full set off 6r polo seats. With need of a little repair to the fabric which is fine. The predicament is do I get the rears fabricated to be able to fit. I can't weld. Or do I just keep my eye out for a another set of rests which bolt in. Any help and guidance would be amazing. I'm in wolverhampton so if anyone knows anyone with the ability to help out I would appreciate that too.
