We've got a '63 Cue-Tease and a '64 Bongo (the two player Ballys before and after Star-Jet.) if you need some Head dimensions, let me know. It may be easier to build a new one than source a replacement. It's pretty simple joinery.

Still hoping to find a Star-Jet of my own, had a few slip through my fingers, until then, best of luck bringing yours back. I'm slowly building a Dixieland myself, started with just a populated playfield I found at a yard sale while driving through Las Vegas years ago. I think I have most of the parts to get started on assembly, the problem is finding them all in my store room...
