Q-jet for '77 403

Hey everyone, looking to replace a defective Edelbrock with a somewhat more original quadrajet for a 1977 403. It would be an M4MC code with numbers like 17057259, 552 or 555. give me a shout if you've got anything close.
Thanks

I have a runner here with a new kit installed in it. It's from a buick and jetted for headers and 10:1 compression though. May be too rich for a stocker.
