CJ7 rear wheel wells do not directly fit a CJ5 due to differences in the body design and dimensions of the two Jeep models.

The 1975 Jeep CJ5 typically comes equipped with the Dana 30 front axle and the Dana 44 rear axle. The Dana 30 is known for its lightweight design and good strength for off-road use, while the Dana 44 offers increased durability and is often found in heavier-duty applications. Both axles are popular among off-road enthusiasts for their aftermarket support and upgrade potential.
