Alright, well ive never tried to cut one out but if its any issue at all i can use some glazing tools

if the razor knife wont do it an electric fine tool WILL its what its made for,(might of been what you saw used) and my dad has one so im sure i can use it.i figured it would have to go under the glass too, it shouldnt really be an issue,. Damn, my dad built his 70 mach 1 drag car with a 460 and ported scj heads that runs on a n enderle alcohol injection setup COMPLETLEY by himself, including fabbing the floors, headers, and frame himself, so if i cant do it, i know he can. this should be interesting to say the least, im sure itll be difficult but i bet money it can be done, and be an easier altyernative
