non-fender replacement necks. Is there a source?

I can find Fender style shaped replacement bass necks till the cows come home, but I can't seem to find any other style. I'm looking for a no name replacement bass neck in a sort of Ibanez Sound Gear style. All I can seem to find are P and J style no name bass necks.

If you know of a source I'd appreciate knowing about it. I just want to dress up one of my Glarry basses that is an Ibanez style with a neck that has a maple Fret Board.

 

But you’re assuming I want it for an Ibanez.

The thing is there are all kinds of J and P ‘style’ necks being made that will fit cheap basses like Glarry’s P & J ‘style’ basses, but nobody seems to be making similar replacement necks for Glarry’s Ibanez ‘style’ basses.
Looking for these but different with Maple FB, binding, etc.
