I see you are in Norway, so local sign shops might not have the latest and greatest high speed vinyl graphic printing machines we do here for fairly cheap prices.
I truly understand the desire to want those specific flames...I fell in love with the harley truck style I have now back in 2007, in the base exchange parking lot on Marine Corps Base Camp Pendleton in California. It was a long bed, blue truck like mine with the black and grey flames. Pristine, brand new, clean. Loved it. I settled for a 2010 black Harley truck long bed and just wasnt happy with her just because it wasnt blue, and wasnt that style I fell in love with. Traded her on a 2012 CTS-V sedan in Opulent Blue...then less than a year later, the Caddy was stolen in Louisiana and dumped in a bayou.
I found the blue truck in Texas while I was in mourning over the Cadillac. Now I wouldnt sell her for anything. Its my dream truck.
SO, I understand that if you get some thing in your head, you want that thing, not something a little different. Of course, I think I am going to do what I think might be a cooler improvement to the flame job on mine in the near future!
If you want, PM me with your email address. I will take a bunch of nice pics of the flames from front to back on each side and maybe you can have a skilled painter scuff your truck and lay out the flames, shoot em, and then clear over them so they look stock.
