206 7-inch Double Tape Frame

Hello everyone. I'm looking for a 7-inch double tape recorder frame for my car. There are 9- and 11-inch tape recorders available, but the one I want to install is a 7-inch Sony XAV-AX3005DB model. Is there a 7-inch tape recorder frame for the 206? No matter how many places I ask, no one has one. Every sound system I go to tells me to cut the original tape recorder frame and fit it that way, but that's the only way it'll work.
