Yes, they were Canadair Sabre 5's by then. One thing to check though is the serial number, as there was a mix of slatted and '6-3' wings issued. For example, XB981, 'Q', was fitted with the '6-3' wing.
The Academy 'Mig Killer' kit is probably about the best out there, and can be built OOB with the '6-3' wing. I built one in USAF Korean war colours a few years back, and have another to do as a RAF bird, and it's a very nice kit at a reasonable price.
The fuselage should be slightly wider for the Canadair Sabre, but to be honest, it would be darned difficult to tell in 1/48th scale. Also, if you wanted to do a slatted wing, although it wouldn't be 100% accurate, it could be done from the kit by engraving the slats in the closed position, which would be passable.
