The winch mounting plates for these bikes are no longer manufactured. This has been the case for numerous years. When I had a which installed on my 300, I had to get a winch plate custom fabricated by a gentleman. Who also installed the winch for me as well. This is pretty much the only avenue you can really take if you want to install a winch on your 300. Once a plate is fabricated, drill some mounting holes and utilize some ubolts to secure it to the front bumper.
