Whoops- yeah, that's a tad redundant...
I'm a little unclear whether the top/doors come off a cj or yj (I've never seen doors like that before.)
Figured all the experts on here could ID it lickety split...
I sent that photo to our customer service manager, who's been here for 25 or so years. She does not recognize them, so definitely not Bestop.
She thinks they might be from a company called Fleet Air. But Kayline could be right too. Both companies are long gone.
The Jeep soft top/door business is littered with the remains of companies. Except for this one company that's been around for over 50 years. But who's bragging.... :-)
Anyway, the difference between YJ and CJ tubs is pretty minimal, so it probably won't matter where the doors come from. The difference is in the windshield, so you might have a slightly off fit, but it won't be great.
$499 seems a decent price for just the top. Consider the doors a freebie.
And the doors you have now should work just fine with the top.
