In addition to this...
The canopies...they are different, one has the "flat" back, the other is the more rounded/blown canopy.
One of the main gears is pretty warped. I've built 6 of these kits and have another in the stash...every single one of em had the warped gear...just bend it back to shape, easy fix!
The Korean era F-51 boxing is the same, with the addition of the later prop, and you get rockets with it.
All in all, the kit is pretty rad! I'd pay the 6-7 bucks on this before I'd pay 2 bucks for the Tamiya kit. Recommended...get some!!!
