Headlight Doesn't Fit

[Filastein]

Bought the pair of headlights off fleabay as new Magneti Marelli units. The driver's side parabolic lens was broken and the headlight didn't fit. The seller has been less than helpful (love to drop his name here but I imagine it's frowned upon). Anyway, I had sold my 'fried eggs', which left me stuck. Sooo... back to my least favorite auction site and a different seller for another driver's side light. Same MM box, same part number, and it doesn't fit either. Exactly the same gap below.

Before shipping the original light I verified it still fit the drivers side. I have marked the latest light's tabs with paint and it was dragging on the inner right side more than most but all tabs had witness marks so they're finding the slots. I'm starting to think it's the connector.

MM part number is LUS4362. Has anyone experienced this before?
