I recently started another Strat partscaster project, and the surprise I wasn't expecting was the fact that a standard tremolo claw would not fit in the spring cavity. The previous owner of the guitar body drilled holes for an import-spaced (30 mm) tremolo claw instead of a vintage claw with holes spaced at about 34 mm. I was disappointed.So I had to find a claw with holes spaced at 30 mm. Unfortunately, all the 30 mm-spaced claws are made of cheap metal, including this one. But this was a reasonable price, so I thought I'd get one and maybe upgrade to a better one someday.It works fine, it fits the holes, and the springs hold well; and I don't think anyone's going to notice or care that I have an import trem claw.The nice surprise is the notch on the plate between the screw holes and the claw ends. That's where the ground wire gets soldered to the claw, and I have to say that notch was a big help--I got the ground wire soldered there on the first try without any struggle. I was thrilled. Typically with a vintage style claw, that part of the plate is flat, and anyone who's done it will tell you what a pain it can be to get a good spot of solder to stick on that flat part of the plate. That notch helping me nail the solder joint on the first try was worth the purchase all by itself.
