My new tank came in a few days ago, thanks very much to Matt Hummel
Trying it on my bike, to see if it clears the master cilinder, as the toaster tank I am currently using didn't and had to be slightly altered on the bottom to fit.
But this tank clears everything perfectly, probably made for the dual disc setup.
Insides are perfect, outside does have some rust as a previous owner started blasting it, but never finished.
I will have it painted black with white pinstripes, luckaly there is enough of the original stripes left to have them copied.
