Which assembly carries the difference, Robin: the arm interface itself or an added mounting plate? I would not infer that from the changed label suffix alone.
Our FR5 mounting plate has a boss the approved drawing never showed

Added plate appears different. Arm suffix changed too. Seller just says equivalent, with no assembly comparison.
15 pointsSend the approved drawing revision with photographs identifying the delivered plate and its markings. Ask the technical contact to explain the difference before anyone modifies your adapter.
8 pointsWe once spent a call discussing the arm when the package builder had changed a separate plate. An overview and a close view together helped. One beautifully cropped photograph left the important boundary out.
2 pointsJack, yes. Also ask for the supplied plate drawing. Robin can describe a boss without knowing every functional difference hidden behind it.
12 pointsAsked for that drawing and a comparison against revision C, which the seller approved before purchase.
10 pointsDon't settle for another distant demonstration either. My seller's video managed to hide the tool at every useful moment. Your actual mounting detail needs to stay identifiable if they use a video to explain the change.
1 pointsAnd if their answer is a different adapter, include the changed tool position in the review. Making the holes agree isn't the whole job
19 pointsCaleb, Robin should also get the option of supplying what was agreed. We are getting quite comfortable designing around their substitution before they have explained it.
21 pointsAgreed with Owen. Compare the original route and any proposed alternative, including who pays for the design and checks. Neither route is accepted just because someone can draw it.
20 pointsOriginal plate requested. Seller says unavailable now. Their technician confirms the delivered plate changes the adapter stand-off.
17 pointsThen keep that stand-off in the load and access assessment for any alternative. The old checks describe the old arrangement, even if the same fingers can be reused.
16 pointsHave they provided the drawing now, Robin, or just the explanation about stand-off? I'd want your installer working from the same defined assembly as their technician.
7 pointsDrawing supplied. Installer is comparing it with the approved assembly. No agreement to alter our adapter or accept substitution.
8 pointsWho would own the revised assembly and spares details if the alternative is chosen? Installer and supplier need the same answer before this becomes their favourite thing to refer back to each other
