One of the topics of conversation at the excellent IPMS National (U.S.) Convention this year, at least among the folks I talk with, was the ongoing lack of a good injection-molded 1/72 (or any scale, for that matter) FJ-3. Note: I have provided material on it whenever asked and a previous post, http://tailspintopics.blogspot.com/2011/04/fj23-fury-redux.html, illustrates a lot of the detail differences in its configuration over time.
Since there is a pretty good 1/72 F-86H kit available and it has a bigger inlet like the FJ-3 (it had a more powerful engine), there has recently been a discussion as to whether it would be a suitable basis for conversion. Suitable, of course, varies by individual, ranging from minor alterations to, as the late, great Bondo said, "practice bleeding".
Herewith an illustration of the basic differences (the F-86H has the wing-tip extension and many detail differences but that's no hill for a stepper; the basic empennage is pretty close):

The consensus was that if you just had to have an FJ-3 now, the Falcon conversion (which is still available) is the better bet; it consists of fuselage halves and a pretty good canopy but no decals. This R.J. Tucker's build combining it with an Academy F-86. Note that the F-86 horizontal tail might be too small. See more photos and a summary of the build here:http://www.arcair.com/Gal1/101-200/gal142-FJ3M-Fury-Tucker/00.shtm
As of this writing, the Falcon conversion is available from Hannants and Falcon (click HERE). I couldn't find it on the Squadron or Sprue Brothers website.
The best single reference is Ginter's monograph Naval Fighters Number Eight-Eight:
