I've had an odd few days in the garage this bank holiday weekend but have managed to get the doors and wings on and am generally pleased with the fit.  It is never going to be a contours car but it should look reasonable.  I've noticed on a few YouTube videos and in particular those by Matthew Randal that I should have some screws down the front overlapping edge of the rear wings to secure it in place which is my next step.  After that I am going to focus on the door catches which do not work well currently, they need stripping down and shimming, at least I hope that is all they need.  I'll post some pictures next time.
