Fixing Jazzmaster bridge problems

longjaw

Following on from this thread I'm still having a couple of problems with the bridge:

1. Strings rattling behind the bridge - I'm sure I saw something about a device that fits behind the bridge that increases the string angle of the strings and getting rid of the rattle (a bit like a Bigsby B7 does) but I can't for the life of me find it!
2. The grooves in the string saddles are too wide for the top 3 strings, so when I'm bending strings they're moving and choking.

Any ideas for fixes chaps?
