hey everyone, I recently came into 2 allparts long-style gibson vibrola systems and upon trying to install one on my sg, i noticed that both have had the same problem and i was wondering if anyone has experienced this same phenomenon.

the spring piece that holds the string plate where the bar is attached is supposed to sit in a slot on the frame of the tailpiece that's bolted on to the body. for some reason, whenever i put any tension on the strings or even try putting strings on, the spring pops out of the slot.

i hope someone can help, because this is starting to really frustrate me!

if you need any reference as to what parts i'm trying to describe, just let me know and i'll try and post some pics.

thank you.
