Since the reference car and my car are both in pieces, neither the owner nor I know what fills this gap. What information am I missing to complete this part of my build?

From the dimensions you'd offered me it appears your tray is short 1" (front to back) as it should be 17 1/2".
So, if the curve appears to fit nicely, I'd suggest you cut another board, same curve but extend 1" forward.
The width you'd offered was correct at 53 3/4". You mention yours is considerably short on each side. If that is the case, there is something amiss within the metal (package tray) framing of your car.
