Do you have a write up about the shroud mod?
It was quite simple. I used a Dremel type rotary tool to cut along the diagonal seams where the white lines are in the pic below (that's not a 3fe shroud in the pic but close enough). I drilled the upper and lower parts and zip tied them together with two ties on each side. I also zip tied the lower section to the radiator where the two white dots are in the pic. Now I can cut the ties, remove the bolts and pull the top piece off to access the fan, belts, hoses, etc. It seals up just fine and funnels tons of air.
