Thanks folks, I will take photos of the before, during and after....hopefully none of my in tears or the sheet in tatters.
I think back to my first Shelby, A GT500KR, I collected it at a local 7-11 from the haulier, I took it immediately home and tore into the dash like an idiot, I got the build sheet which was perfect and, although being fairly careful, opened it up rather quickly. Thankfully it was in very nice shape and didn't fall to bits.
