same order, different bracket suffix

Our FR5 inspection-sample package has arrived with a different suffix on the tool bracket from the one the seller confirmed against our fixture drawing. The delivered bracket also seems to put the fitting on the opposite side. I've kept our tooling off it. Seller says equivalent, but hasn't sent a comparison. I'm trying to get a proper answer before our installer spends a visit finding out which bits don't fit. What would you put side by side in that request?
