Q: Will this fit in a Squier bronco bass?

Broncos have smaller head stock. You just have to measure everything.

Q: Would this fit on a 1968 vox skybolt iv v282

I've had excellent results using these tuners. Sometimes you must carefully use a Dremel tool to increase slightly the inside diameter of the holes for the bushings. Likely will need to mark and drill mounting screw holes. Don't drill all the way through the headstock. Use tape on the bit to limit drill depth. They're great!
