Holley 1920 missing parts - time to swap?

TL;DR - My carb is missing parts - should I swap it for a new 2 bbl, search for parts, or buy another used 1920? My budget is about $250.

We started a rebuild on my 1920 and it is missing the baffle, float spring, and pump return spring. The float is also bad (edit: nitrophyl, fuel soaked - supposed to be 7.5g). We're not sure what best move would be, seeing how hard it is just to find the floats. We can get the float spring from Mike's, and according to Holley 1920 diaphram return spring we may not need the pump return spring, and the baffle we may be able to cut ourselves, but I wanted to get people's thoughts about it. Also, has anyone ever tried to 3D print a float?

Most other threads reference Walker parts but I've spoken to them and they've discontinued the 3 for this carb. This posting Holley 1920 float!! gives a NAPA part that I can't find.

We're considering going to a 2 bbl anyway, though then we get into researching a new intake manifold.

We can find some 1920s on eBay that appear to have the parts intact, but I imagine they would need a rebuild as well (which is fine, since we have the kit), but there's no saying whether or not the float is good.

List # is 6156, for reference.

Any insight would be appreciated! This is my first time around with this stuff. Thanks!
