Fast forward to 1983, when Revell reissued the kit under the "Street Demons" series. One of this kit's beast features was the flame decals which were applied to the hood and body, meaning one only needed to paint the fenders white, with no need for tedious masking and color matching unlike some of the other Street Demons series kits:
Revell and HOT ROD magazine teamed up to release an entire series of HR-branded kits, including another go 'round for the S-W-C Willys kit, again looking much like the orignal issue:
And yet another (not nearly as nice looking IMHO) verision in the Hot Rod series, this time molded in red:
But wait, Revell wasn't done! They released the '41 Willys as part of this three car combo kit, again as part of the HOT ROD series. This must've been released in 1985 or so, when the brief "Fat Attack" street rod trend had peaked:
Finally, Revell-Monogram re-issued the original version of the kit in 1995, with box art almost identical to the original, save for the new copyright date on the side of the box:
There are some parts like the hood trim piece and the perforated grille piece which seem to have come and gone in various issues, but I can't say which versions include which, or if they were in every issue all along. Other than the 5-gallon pail diameter header collectors and the two-piece tires, nothing stands out as eye roll-worthy that I can see or remember with this kit, but being '60s era Revell kits, they can be a bit fussy. That said, if you take your time and mock everything up before painting and assembly, you should end up with a nice looking replica of a mid-'60s Willys hot rod.
