many of the cheapo squires had bridge mount as opposed to string through
if you feel adventurous why not have a go at putting the holes and ferrules in yourself
it requires a bench drill, 1/8 bit and a standard strat string through hard tail bridge
also you might wanna do a bit of research on getting ur holes perfectlcty straight so the are evnely spaced on the back as well as the front
1/8" drill bits can wander a little through a 2" thickness
ogten the holes on the back are a bit out of wack
screw the bridge down and puch the holes through the holes in the bridge about 1/4" is enough so you can flip the body to drill them from the back. you need to mount a 1/8" steel about 1/2" long pin driectly under ur bit and push the body onto the pin on each of the 6 holes you done on the front...that way ur holes on the back layout perfect
btw a hardtail strat sounds really great with stringthrough hasrdtail IMHO better than the standard trem bridge
