This is a great video of the Tamiya 4×4 Blazing Blazer RC model #58029 from 1982. In the comments they said the only thing changed were the springs, from a Tamiya Ford 350 Hi-Lift.
This is an awesome Jeep toy and figure! It is not the normal metal Jeep toy that you associate the Tonka name with, but still just as awesome. Check out the 70’s graphics and quick disconnect tires. Did it come with another set of tires?
