Please find answers to your questions below (in blue)
PS. You should not be surprised that the frame AD004 extends past the strut brackets, it is the same what happened to AD001 before changing the drawing/blank length. Both AD001 and AD004 had the same height. Therefore the bracket sticks out same as per AD001. Please note the master frame at ORA2 sticks out past the bracket (see photos)
Note to your remarks below: 668PQ001 is 1814mm long NOW (after changing the drawing revision) We have not received new stock from MT yet (just airfreighted you 4 samples) Before change, the extrusion was 1828mm long (30mm difference to 668PQ009) . There was no way of mixing up extrusions as they could not fit the jig and they would have been like 15 mm longer each side.
Last time we produced AD004 was in August, before you changed the length for AD001
Hope you understand my explanation above, I will reply Kamran to the concern separately.
