fuel filler could be quite easily moved to the boot... especially if it was going to be an SEi CC (im having a custom ali tank made, with an intergrated swirlpot and baffles... so mooving the filler round the tank one side would be the last of my worries...)
custom top... just be careful how you take the roof off so you can clip it back on! not that youd want too...!
sealing... hummn.... mabe be prepaird for "some" water ingress... no worse than a poorly fitted sunroof... but plenty of door seal section rubber should be a start...
do you really need a how to!... here goes...
tools required:
angle grinder and blades
goggles
mask
firstly connect grinder to a suitable power supply... then put on safty equiptment (goggles and mask) then injoy...
