I used to have a 1973 Jeep Renegade with a hidden compartment under the driver’s seat. The only Jeep I have ever seen one on.
I had a 73 CJ5 as well years ago and I am trying to work out what kind of compartment could be set up under the driver’s seat. I don’t doubt yours had one.
I wished AMC Jeep would have kept the passenger side under seat storage compartment that Willlys and AMC models had until 76.
