Side stand on Vespa Cosa 125

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

Hello. I like to put a side stand to my Vespa Cosa 125 of year

91. In the pagina I have found two versions but It say that they

are only possible to be mounted in English systems of escape and my Vespa is

Spanish, I think, because I am of Valladolid (Spain) and we bought

there.I would like to know if I could mount it, if I have to do

some modification.On the other hand  I like racing exhaust LEOVINCE PX80, this is an option that I am

considering, but I read that the owner must be modified, talks about the cylinder? I want to put this escape in my series motor.Whith this exhaust I could mount a side stand? Thank you very much by everything, I hope that You understand me with clarity because I do not speak

English very well. A greeting
