Upgraded my 17 and 19 MOS slides to steel TangoDown plates for the ACRO. Was using CHPWS aluminum plates prior. Also, the VC-3 did not hold spec over time. Loctite 248 will be the go-to from now on. Luckily I had the Loctite glue stick already and have been using it on equipment for years. Thanks @SoCalDep
