What the size of jumper shunt for AMP 2.8?

Hello,
I would like to buy a jumper shunt in order to put in my APM2.8 on area “GPS”. What the size of these jumpers? 2pin 2.54 inches?

I tried 2pin 2.54 inches but it’s tool large! Could you help me please!

Thanks.

Hugh

Measure the distance in mm between the two pins center to center and that is the size
