The first and most obvious tweak is fixing the lack of seat detail. Resin copies are the obvious fix, but with no option of open canopies, it seemed a waste to me. First pic, sorry for the out of focus, shows the difference masking tape seat belts make. I also wound up some wire for the pull handles that the kit misses. Without this tweak, it looks like the old Revell kit seats when complete. Forty dollar kit, and I can find better seats in a five buck Monogram kit from 30 years ago
