Got the fuel tank put together. Used the Dan Checkoway method for drilling the Z brackets...they were dead down the middle of the holes. Had to take off the leading edge for access. When it was all said and done I was happy with the outcome. I though of taking a picture where the leading edge and fuel tank join (or where I expect the gap to be)...as it turns out there is no gap, they join up so well you couldn' t get a piece of paper between the two...even I wasn' t expecting results like that.
