Hi Dave,
Clamp the TGW21's to the outer W18's.
Fit the FL3 between the TGW21's, with all the spacers, as per the manual.
Do whatever you have to do with the W19 and W20, [in as much as juggle which
side of the W18's and FL1 and FL2 you put them] to get the correct fit. You
may need to put a slight bend [ zig / zag] in the inboard bracket [ W19] to get
everything aligned.
Do not start cutting the spacers at the FL3 / TGW21 position, this will alter
the clearence of the flap to the aileron [ BAD NEWS !]
When everything fits, drill and bolt the TGW21's / W20 / W19 to their
respective W18's.
Easy, aint it ?
Cheers,
Nev.
