3spd column help

[1968CHEVYC10]

I adjusted the linkage on my '68 according to the FAQ article and it didn't seem to help much, it seems like the piece that moves the 2 shift levers on the column is worn out. I tried adjusting the width in between the 2 levers but that didn't really do anything either. i didn't have a chance to look at the mechanism on the hand lever inside the cab, I'm not really sure what I'd be looking for anyway. any suggestions and what could be wrong?

I'm also possibly looking into a floor shifter, what's kinda the best out there as far as price and quality? I'm not looking for anything really performance aimed just something durable that will get the job done.
