Well, you are seeing the infamous Tamiya Panther tank engine deck in there, plus Airfix Saturn V LEM bits (which the Red Jammer Y-Wing used). So yes there is a common detail piece connection with the Y-Wing. Other bits in the Eagle include the M-551 Sheridan engine deck and Revell Gemini domes.
Back in the 1970s, the greeblie bits catalog used by effects modelers on both sides of the pond included quite a few common kit parts sources for bits. So with an Airfix Saturn V, Revell Gemini and Tamiya Panther tank in your arsenal you could detail up about 80% of the studio models used in film and television productions at the time.
