Doing nothing was to easy...
Got a SP GP20 from the cabinet and use the dimensions and shape of the turbo stack to build my own from styrene. That will make the GP18 closer to a GP20.
The rear vent should be moved more to the rear and a winterization hatch added between rear vent and the dynamic break vent. I am not sure if I will do that more serious modification to the roof.
This photo http://www.rrpicturearchives.net/showPic...id=1898915 shows the correct position.
That's what I am trying to do.
The hatch is from stock and fits quite well. I will refrain from the risky business of moving the rear vent. The turbo stack needs sanding tomorrow when the glue has set. The old two stacks will be removed.
