Hi Bulldogboy, thanks for the information.
On ebay there is only one set, and it's too expensive to me.
In the Japanese auctions i don't have any experiece, it's a little bit complicated, my Japonese is very bad...just kiding
I'm hopping to find here someone that will have some 3xv silencers, and will sell and ship it to Portugal.
Anyway, thank you for all.
