From searching the web, it seems Squier use a 60mm post spacing (or even 63mm - I've seen both figures used) but that's about it. And I don't think you can get Squier bridges easily, and I doubt they'd be better than your current one.
I prefer the wider spacing as it moves the posts outward a bit and more of the post is supported by the full thickness of the body.
But to get a better quality bridge, plugging and redrilling will be the best option. Just be careful to fully support the underside of the trem claw route when putting the post inserts in, or you could end up doing what I did:
Also, you need to check the depth of the inserts against the depth of the body, as you don't want the posts poking through the bottom of the trem claw cavity as the dimensions of your kit may not be the same as those of a Fender. I filed down my inserts to give me a 2mm thickness at the bottom of the holes. You may also need to file down the end of the posts so they don't push through the wood if the posts end up sitting really low in the shortened inserts.
