Can't answer your question, Jim, but wanted to point out that the authorities take a VERY dim view of such activities. Unless you can get a BMIHT certificate from one of the other numbers fastened to the body (not just engine, gearbox, etc.), you might be better off throwing yourself on the mercy of the DMV (or whatever the FL equivalent is). They will have a process for assigning the car a new VIN number and creating a proper title.
Otherwise, you risk jail time for tampering with the VIN (ie attaching a new VIN plate).
