Sean - Welcome to NICO.
The good news is there are now many G50 (90-96) model Q45s available in salvage yards. Also, in the classified seciton of the NICO forum there are some members parting out various models. I have found the "pull it yourself" type salvage yards sell trim items at very reasonable prices.
What color is your Q's interior? There might be a member who knows of a similar car that is being parted out.
Also, if you haven't already seen it, visit
www.Q45.org and browse the information that is available for G50 owners.
Cheers,
Craig
