The Monogram kit (and the Hobbycraft 1/144 kits) depict the wing too high on the fuselage and I went to the trouble of correcting it on this build.
It is a lot of work but to me it is worth it. Your Call. I scribed with the dental pick exactly at the intersection of fuselage and wing
with the dental pick and then when nearly through finished the cuts with the little Exacto saw that fits in the #11 blade holder.
