<VV> brake cylinder removal early

[Bill Brafford]

i have a 63 spyder, has anyone else had difficulty removing the rear brake cylinders? there are two bolts that hold the cylinder on, one of which is inaccessable.  after several weeks of trying to make tools to fit,  contemplating chisling the bolt head off, or grinding the interference from the edge of the swing axle, the cylinder was "rebuilt in place" hope it holds. 
has this situation presented itself to anyone else, if so what was your solution?
