I don't know how much harder I have to look. To the best of my knowledge Monogram put out two rear engine kits that were replicas of real cars. One was the yellow Prudhomme Carefree car and an all red Mcewen Carefree kit. These kits came with the xmas tree and the extra crew figures. If they came with wiring I'm not sure as I never had either of them. If they made any others then I am not aware of those and I would love to see some box art.
As for the picture shown I am seeing a multi color, Go Navy, English Leather Mcewen car that was a single kit as well as in the double kit. That was a Revell rear engine kit. And some of the Revell kits came with wire front wheels and some came with solid front wheels. Plus, if this were a reissue of an old Monogram kit then why wouldn't Revell market it under that name like some other vintage reissues that they've done in recent years?
Now, if any of my information is incorrect then someone please elaborate on what I should be seeing. But, as I said before, either way we are going to get something good.
