Holley 1920 missing parts - time to swap?

Finding all the parts is the crappy part. I have a rough carter bbd and the intake and some of the linkage.

I found what really woke my 1920 up after the hei ignition upgrade was a bigger main jetting. 3 up on the mains really woke the car up for the upper rpm. it was even leaner jetted by one size than most 1920s I have seen. Notas good as a super six. But good tuning and tinkering pays off
