U7 & U8 look about spot on, to "the eye" it makes you think its wrong, but its to do with the width of the pedal box when using a Type 9 box,
its quite a common mistake when fitting U7 , the brain sort of tells you to fit it in line with BR9, similar to how U8 is positioned directly in line with BR8, the bottom diagram on page 38 gives the spacings for U7 & U8 from the centerline
Also, don,t forget that when your chassis is fully welded you,ll be removing the steel of BR10 which is between U7 & U8 , it,ll all make sense when you come to fit the gearbox
Nice work Michael
