Hello ukhair79 ... maybe JRob could best advise you as he has taken scissors to his systems before to re -shape them !! He cut one into a mohawk for a party and it looked great ! LOL !
I`d be afraid to re -shape mine unless I had a spare standing by in case of a disaster..... I guess it can be done, especially knowing that stock systems are often trimmed at the perimeter before being cut -in, but personally, I wouldn`t chance it on my own systems --not saying you shouldn`t or that it`s a big no -no, just I`d be afraid I`d make a hames of it and ruin the piece totally. I wonder would you be better off to order a new system first, while `nursing`your old system along while waiting, then when it`s delivered, you could chance re -shaping it --at least if it goes wrong you`ll have the newly -delivered one to fall back on. If it goes well, you`ll have 2 good systems to swop between ,and you`ll have gained some new valuable experience. Paul.
