All (I think even the first year even though it has a different flange)
1500 wings - but... it is not a direct replacement, you have to be
able to take the good 1500 ring gear and press out the splines, do the same
to your worn valkyrie ring gear, and then press the good splines
into your valkyrie ring gear.

You could just buy a new Valkyrie ring gear, but then you'd have to
have enough skill to shim it properly - maybe easy, maybe not, ida know.
I got the guy down at the NAPA machine shop to do the pressing for me.
