After comparing the outlines, I found that the proposed approach overlaps the door handle even though the workpiece itself clears. That explains the misleadingly comfortable result in my initial sketch.

Use that measured layout to review the complete approach and retreat offline. Include the tool, cables and service access, then ask the integrator to assess a revised mounting arrangement.

The buyer has suggested choosing a larger arm. I'm unsure whether that would address the access issue or simply increase our purchase while leaving the obstruction unresolved.

Going larger should open up mounting options. It might be the most straightforward option to explore.

@OmarArcher0404 The handle overlap gives us something concrete to fix. No assessed layout yet, so the arm stays on the shortlist.

The obstruction is a useful finding, even with the final layout still open.
