The delivered FR10 adapter has a raised face where the confirmed drawing shows a flat one. Seller calls the different suffix an equivalent option. Our tooling is still unfitted. I need them to compare the actual assembly, including the housing's position at release, not just tell me the bolt pattern matches. What should that request name?
Name both adapter identities, your agreed tooling assembly and the changed mating face. Ask for the delivered-versus-agreed comparison and the option of supplying what was ordered, before assuming a substitute must be accepted.
