Factors that would prevent a fit include:
* Frame Differences: The frame of a 1979 Power Wagon is drastically different from most modern trucks. Even older trucks of different makes and models will have varying frame dimensions and attachment points.
* Mounting Hardware: The blade's mounting system – the brackets, pins, and possibly even the push beam – is almost certainly custom-designed for the Power Wagon's specific frame.
* Blade Width and Weight: The blade's size and weight might exceed the capacity of another truck's frame or front suspension.
While you *might* find some overlap with a similarly-sized older truck of a similar vintage, it's highly improbable without extensive fabrication and modification work. This would likely involve custom-building new mounting brackets and potentially reinforcing the frame of the receiving truck. It would be a significant project requiring welding and metal fabrication skills.
