Batboard

I recently acquired a lot of repair parts for older Motorola HTs and I have 2 that I have not been able to identify:

50-83064J01 "SPKR PM"

50-83466D02 (previous owner wrote "for speaker mike" on box)

I have been through all my manuals for radios I think they might be for and can't match the numbers. Does anyone know what they are for?

Thanks
