My GST-1 had a US-standard thickness body (though they can vary a bit between years but it was basically the same as my Dave Gilmour Strat), but I can't vouch for the neck pocket depth as I didn't ever need to measure it, but visually it looked similar to the US Strat.

But the GST and GSH kits come from a different factory to the ST and STA kits, so I don't know if they are the same thickness or not.

If you really need to know, I'd email Pit Bull direct and ask. They are normally pretty quick at responding. service@pitbullguitars.com
