Thanks for the good luck wishes!
Yes many people have advised me to shim or "block" the tremolo bridge effectively creating a 'hardtail'. My main goal is to hopefully increase the sustain and have more control over the action. I was planning to go with a gibson style wrap around bridge or bridge/tailpiece.
But, I just now learned what the strat 'hardtail' style bridge actually is. That looks like it would do, but one of my pet peeves is having to thread the strings from the back of the guitar. It's just a pain to feed the string up the cavity or to retrieve a broken ball end that is stuck up there. I do have an old mij strat that I'm wanting to convert also, and I think in that case, I'll definitely go with the hardtail bridge since it will probably just drop right in. There is one on SM that is top loading... only $20, might be a worthy experiment.
