Where Can I Find...
 

I am currently in the process of replacing the driverside floor pan in my '91 lx and I realized I need to replace the piece that goes under the front of the front seats and over the trans tunnel. It is where the front of the front seats mount to and I don't even know the proper name for the piece and I can't find it anywhere. Anybody with any insight is much appreciated...
Thanks.
Sorry if I sound stupid.
