Jp157 Trem arm

I received a used Jp157 that I ordered from a Guitar Center a few states away today but it did not come with a trem arm, the listing did not mention it nor did any pics show one so I assume whoever sold it to them didn’t have it. Is there anywhere I can order a replacement?

I am seeing a few different styles on Reverb, and was curious if anyone knew if this one would work?

Thanks in advance! The guitar feels and plays awesome, really excited to throw some riffs down with it.
