Finding a longer clutch adjustment rod?

I have been thinking about my situation with my pedal not coming all the way back up even though my clutch is relatively new and I’m all the way at the end of my clutch adjustment rod. I’m not sure what clutch is in my car because I didn’t order and install it. Maybe the fix isn’t that I need a longer clutch adjustment rod but that I need to install a smaller over center spring? Or possibly remove it all together? Should that allow the pedal to come back up easier? Right now the clutch only engages just above the floor and I’d like it to engage right at the top after a small amount of free play. I can’t go out any further on the adjustment rod. I’m pretty sure the linkage and z bar are installed correct with minimal play.
