Working on switching over my 76 corvette to a 750 double pumper that has a performer rpm intake and working on the throttle cable setup. It had a 600 street warrior intake which was to small after doing heads/cam/headers why the update. I think when the carb was swapped the throttle bracket was modified assuming from qudrajet.
So now I am torn between doing a 69 style factory cable setup. Looking at this diagram I think I need 29424, 29404, 42773, 29432, maybe 29411. Does this look right? https://www.topflightautomotive.com/...xoCJycQAvD_BwE
Or should I consider a lokar setup like

I’m not quite sure I understand the first part of your post, you had a Performer RPM intake that was too small after your other engine modifications, but that’s still what you have now?
Your throttle cable appears to be the factory piece, although that bracket doesn’t look like what came with the Quadrajet. No reason to change the cable out unless you want to replace the clip that holds the sheathing in the cable bracket.
When my car had a Holley carb on it I used an Ebay version of their adjustable throttle cable bracket with no issues.

Tried to clean up my wording. The intake is fine but needed to upgrade the 600 cfm carb.
Also side question love your valve cover breather layout. Any more details? I am trying to cleanup my engine bay

The PCV valve itself is just the parts store special Spectre canister, it has a matching chrome breather on the passenger side valve cover.
The hardest part about running them was trying to get a correct grommet for the odd size hole in the aluminum valve covers. I have roller rocker arms which prevented me from using the factory baffle. I had to get a special baffled grommet and opened the valve cover hole to the stamped steel valve cover spec. Nothing you’d need to worry about if the grommets on there now are the correct 3/4” ID
The line to the carb is just a heavy duty 3/8” vacuum line that I put one braided loom on. I’ve since taken the loom off and am on the lookout for a smaller OD line because it looks a little large in my opinion.
