Sounds like I've sorted it! Stuffed the springs with kitchen towel then held it all together with duct tape.. course its pretty much impossible to use the trem now, but I never used it beforehand anyway ;) I might try some Schaller springs if I can find any (any idea where to get em from?), then see if I can get the bridge set up to fuction as a proper trem with no squeaks! It all seems to stay in tune now for some reason, before I stuffed it I was having problems keeping it in!
Thanks for the replies :)
