What sized rim? The standard model AT1/AT2 had an 18" front rim. I'm pretty sure the AT2MX had a 21".
And a general warning that you can't trust Zedder 100%.
I've got a black painted 248 hub in a 21" alloy rim that's dated mid-1980: I've been guessing that it's from a YZ100, but haven't really looked.
Plus all of the twin shock DT125/175 (and 100s?) used that hub, not just the couple listed.
If your wheel has pretty spokes, I'll take it off your hands in exchange for other old bike shit or cash...
