Questions on Squier/Fender IV Basses

I've been wondering lately, is there any difference between the hardware & electronics on a Fender VI Bass and a reguler model Guitar such as a Jaguar?

I'm specificly wondering are the bridge, tremolo, trem springs, and tuners built any different to account for heavier string gauge/tension? And lastly, are the three single coils specificly voiced for Bass, or are they just regular Guitar pickups?

And just on a side note: Do VI Basses play more like 6-Basses or Baritone Guitars? because I belive they take about 24-84 gauge strings which I think could go for either Bass or Baritone.

I've also been wondering, is the base-width of the neck wider like a Bass, or thinner like standard Guitar? And if it's more like standard Guitar neck width, could you put the neck on a different body?
