This may be a silly question, but I can't find an answer anywhere online and I'm brand new to using power meters!

I have a garmin vector 2s and changed the pedals out successfully and everything seems to be working fine.

However my old pedal set up had like a 20mm pedal extender on each pedal to keep my knees straight up and down. How am I supposed to use the pedal pod with those? I'm assuming the pedal pod strap that wraps around the crank must connect to the vector 2 spindle in the pedal. How can this work if I add the spacer? I have not figured out how to remove the extenders from the old pedals.

Thanks for any feedback!
