1954 speaker ideas

[Flysocal]

Mocking up my cab and need ideas on where to put my speakers. Kick panels would be good but my left side is occupied by e-brake and cup holder. Rear cab corners are occupied by retracting 3-point seatbelt. The original spot has room for 1 5x7 which is fine I guess. I'm not going to run a bangin system. No amp no sub just a basic system for radio. Any ideas how to mount a 5x7 speakers in original spot? Or any better ideas. It would be nice to run 2 speakers. Mounted controller in glove box.
