Convertible door glass lower channel/regulator track

Hey 68-70 convertible owners. Can any of you tell me if this channel attached to the bottom of the glass is the same for convertibles and hardtops ?

My door glass was missing when I my the car, so I am trying to ID what I need for parts. I have the SS vertical trim and I am buying new glass. so I am hoping I just need to get the lower channel.

thanks
Chris
