The nose gear fork, B78, needs to be shortened. The square bottom of strut, B57, should be at the front curve of the fork. Parts C56 and C53 also need to be cut to fit.
The retract mechanism, parts C27 and B80, is actually for the F2H-3/4 Banjo, but since you can't really see it inside the nose gear bay, I didn't correct it.
The nose gear should be farther forward. The U's for the placement of the nose gear strut, on parts C25 and C14, need to be cut off and moved forward and glued like the red U's in photo.
Forward corners of nose gear doors should be cut on an angle.
