Shimano 105 FC-R7000 crank cap?

I’ve managed to lose the little plastic cap that goes on the left crank arm for my Shimano 105 crankset. I can’t seem to find an exact match online, but do you think this one would work?

Maybe? I’ve had Ultra caps not fit D/A cranks - it way too long or maybe vice versa. It’s been a while, so I’m not exactly sure.

My surmise is that you’d be better off using a cap fro a 11sp crank - the 6700 is a 1st gen 10 speed crank.

Edit: Did a little searching. Looks like the longer caps were for earlier models. Short caps are for current models. competitive cyclist.com has a cap for Dura Ace 9100. I’d try that.

It’s the Y1P417000

Thanks!
