[Motorola] Spectra 860 MHz

[Glenn Little WB4UIV]

A Spectra D45KMA7JA7AK followed me home from the Shelby hamfest.
It appears complete less the front panel.
The radio is currently programmed (at least by the tag) to receive 
860.7675 and transmit 815.7625 and 860.7625 MHz.
The date on the tag is Jul 31, 89.
It has options W496BA, W432AA, W71AR and W70BE installed.
Can this radio be moved to 900 MHz hamband?
Or do I have parts?

Thanks
