ok here's an update... was away in italy for 7 weeks, and the second day i got back i decided to do this:
the box wouldn't fit in my hatch properly so i decided to take about an inch of depth off my hatch... went through 11 cutting discs to get the job done :pface
the aftermath of the dremel session
after another 15 hours of so of bodywork this is what i ended up with. pretty happy with it; good enough for canada
carbon fiber glued on and starting to layer on the resin, looks like it's gonna work out pretty good
