I just had my 62 reissue strat setup with heavy strings, 5 springs, and a flat bridge. After getting the guitar back, I went ahead and took the sticker off of the tremolo bar hole and tried to screw in the tremolo bar, but alas it wouldn't screw in. Finally, after numerous tries, it screwed in, but was really stiff even after one turn (it doesn't move or flop down at all). So I took it back out, and got it in again and it is still stiff, and I noticed that when the bar is hovering over the pickups, it is higher than when it hovers over the body past the bridge, which I'm guessing means that the bar is crooked inside the hole. I tried extremely hard to get the bar to go in straight, but it just wouldn't. I assume that it is stiff from the spring claws being tightened and having five springs, but that's just a guess. Any ideas of why it is like this?
