I agree with everyone's advice about redisclosing ETILs. Unless the customer requests one or you see some value in it, you can skip ahead to the final TIL. As a general rule, you should always do a final TIL. Mandatory final TILs are cheap insurance and will catch the type of changes you described. By disclosing the deal exactly as consummated, you make it MUCH easier to audit the documents. Easier audits mean time and money saved.
