Careful, there are two or more versions of this belly pan pattern from a few makers both with and without cutouts for stock R3 crash bars. I have seen folks buy the untrimmed version and then find it doesn't fit with their stock crash bars.
Some also come with brackets but are not pre-drilled or with clear 'dimples' where they should go.
Others like
@Stillserving are not pre-drilled either but do have 'dimples' marking the hole location.
Then there are the predrilled ones with brackets.
