125-200cc Bottom Motor Mount Bolt

So, I had a great ride today but when I got home I noticed that my bottom motor mount bolt was gone for my 2009 wr300.

I don't have my manual with me and I am not sure if the bolt dimensions are called out in there anyways.

Is this something I can get at a place like Tacoma Screw or do I need a husky specific part?

I did some searches and generally the issue has been the upper mounts which are still fine.

I'd just buy a metric bolt/lock washer/nut,,grade 8,just take a measurment from mount tab to mount tab and add an extra 3/4" to the length,,use the front engine bolt for the size diameter,,no need for husky bolt...

Thanks,
I forgot that I have a parts diagram that I can reference.

Feel kind of silly for posting this actually.

Thanks for the good advice.
