Campagnolo 11 speed shifter questions…

Hello, my right shifter (chorus 11 rimbrake etc) is damaged, probably from overtightening the bolt. I have a spare chorus shifter, which is a bit different, different lever blade branding and some internal differences i can see. Does anyone know if these are compatible?

thanks a lot!!

If I recall correctly, these two pull different amounts of cable.

Depending on which one is broken, you might be able to replace the shifter body with EC-RE300 (newer, white Campagnolo logo on lever hood, rectangular patches of textured hood material) or EC-RE100 (longitudinal stripes on lever hood)

Thanks for your answer James, to complicate things further, I replaced the hood on the damaged one when i got them. I will try anyway
