rear part of monster frame

Hi

I have bought a 2001 m600 monster but the person that I bought it from has cut the 2 pipes off the very rear of the frame to make it look more like a street fighter type bike, but I would like to make it original but fitting a teatray on but need to weld the frame back together.

So if anyone has cut these off and want to sell them please let me know.

thanks

jonno
