This is an model assembly question so please move to appropriate forum as necessary. Hello all, My friend is trying to assemble bushwhacker #3 and he is having some difficulty following the instructions. In looking at his sprue, he is missing the square piece identified in red, but has two similar looking "banana peel" pieces identified in blue. Are the instructions incorrect or was the sprue missing the piece he needed? Has anyone else successfully assembled this gremlin? Thank you, Regards, K.W.
