Re: 1970 Ford Mayfly.
This is the third Mayfly I have seen. I saw a 1966 Mayfly in Montreal about 10 years ago, and for some time there was the remains of one in a wrecking yard here.
From what I remember, the one in Montreal was basically a Custom series model with buckets and a console and floor shift. The one here in the wrecking yard had no engine and just a bit of the interior. All of them were white with red accents and red interior. None of the cars said Galaxie or Custom or anything other than just "Ford" on them. The Canadian one, and the one here in the junkyard had a small decal on the trunk and each rear quarter. It looked like a fly or something. I see the one for sale in Michigan does not have any decals.
I suspect this was just a sales special where a cheap level car where they put on some decals, buckets, console and perhaps a bigger carb or something to grab a few more sales. Sort of like what Ford did with the Mustang Sprint; a dolled up six. I would bet that this car is a Galaxie sportsroof with a Custom series interior and features.
If I recall correctly, didn't Plymouth around this same time offer some budget, stripped down muscle car? I think it was the Road Runner.
