If the bridge routing on the body of your SV-1 guitar is the same as the bridge routing on my Hot Rod Strat, then maybe you could consider replacing the stock LFR with a Schaller Lockmeister, which can be ordered online from Realtone Music:

The one shown on the webpage is the exact same one I have installed on my HotRod Strat, it seems to be of pretty good quality, and according to Schaller they are basically the same as an original Floyd Rose.
Note that Realtone Music also stock them in Gold and Black finishes as well as Chrome.
