Good morning Ed,
If you have a 21/32' accelerator pump cup then you should be able to use the Quadra Jet pump cups. Just be certain of the size. Then you could use an Edelbrock Q-Jet pump in a pinch, remove the cup and install on your existing pump assembly. That would make getting replacement pump cups easier. Cliffs , Mikes and Quadra Jet parts should be able to hook you up with pump cups. I've been successful with the Blue cups
,there are Red cups available but I have not tried them myself yet. A rebuilder local to me uses these Red cups without issues and he sends carbs out of state. Let me know if you're having trouble locating some pump cups.
Have a Good day.
Respectfully,
