Well my english speaking realy sucks big time
so emails is the way to go for me , but thx for that other email im gonna resend on that on to.

I think this are the heads im gonna need but i also need a roller to match it , would been nice to order all from the same place and know that you get quality parts, and what i read in here Bob seems to be the man.
In norway there isnt many with the expertise to setup this kind of parts, and if it was the prices here is 3 times what i pay to get parts directly from us with shipping
