Rod end clutch limkage

[TS69GT500]

Has anyone used the rod end clutch linkage with or without their supplied Z-Bar from Modern Drive Line or
Opentracker?
This would apply to drivers of course not show.
I would like to add to my driver 69 GT500.
If anyone has used either, any comments pos or neg.
I am going add the Scott Drake roller bearing kit to my pedal support and would like to supplement with
rod end linkage if possible.

Thanks,
TonyS
