Need advice on USPc9 FPBS

Will the new style light FPBS [#209296] work on a datecode AE USPc9 without changing the FPS and the FPB itself? TIA

No. AE date code has the old-style FPBS.
Thanks!! And another question: Are there really "light" and "heavy" versions of the TRS on a datecode AE USPc9? I only find one, not identified as either, on HKparts.net, #209266. Thanks again.
