Cheers guys.
Yas may have noticed one thing that keeps bugging me... the seat is a little too far back. This stems from me bending the Revell rear wall, which was 90° vertical, back on an angle. What I SHOULD have done was leave that alone, and put the scratchbuild rear wall on an angle in front of it. The seat is now nearly 1mm too far back, very noticable in 1:72!
The seat is solidly in place, so can't remove it and move it forward (I tried). May just move the control column back a touch (if poss) to make it less obvious.
