@mk one ..
Agreed they look perfect from where I'm standing @mk1benny I was thinking the same as you probably about a year ago when I was embarking on my Cindercone build,but decided otherwise in the end.
If your planning on a total rub down and respray then I'd say go for new decals,but if not then I feel you will get yourself into a bit of difficulty,as the decals are under lacquer .
But yes if you decide to choose a UK based decal supplier,then @gil_m is certainly the best shout as he is very accommodating and if you measure exactly the dimensions of each decal before removal,he can adjust his end before printing.
(Speaking from recent purchase of some 94 Lava dome ones)
Hopefully this information will guide you in the right direction
