Hi,
I trimmed my bodywork panels as much as I could and now, everything (temporarily) fits together. However, I have big gaps at a lot of different places
Sylvian, I've just trial fitted the first of my side panels today with a setup similar to yours (3mm alu floor) and found a gap much like the one in your picture above. Any tips on how you addressed that particular gap? At the top, where the panel meets the foot of the roll hoop my panel sits about 10mm above the metalwork...!
