Holley 1904 Carb

The accelerator pump arm is snapped off on my carb. Anyone know where to find one, or have one laying around?

I've searched ebay for carbs, just wondering what carbs will easily replace the 1904. I know the 1904/1908/1920/1940/1960 are very similar, but how similar are they? I don't feel like fabbing up new throttle or choke linkages? What other carbs will bolt it place?

I have seen where the see-thru 1904 glass float bowls are on sale occasionally... look real cool. Often they are cracked though... need to be careful. They are different linkage than the Ford Autolite 1100 and 1101 carbs. I had a hard time buying a reman's 1100 as well. So unless you find a replacement 1904, you will probably have some tweaking to do. I can't advise on the other Holley carbs you mention.
