Default Carb Info Requested

Hi all,

I'm working on a '68 Quadrajet, Carter #4887S (Rochester 7028262).
Trying to find out what secondary metering rods and hanger were in it originally. Primary jets and rods are supposed to be #73 and #43B. Would like to confirm that that is correct also, as that is not what was in it.

Thanks, Ron.

Carter 4887S is actually an aftermarket replacement for all 1969 Pontiac 350, 400, 428 Qjets, exc. Ram Air, as it has the primary pull-over enrichment system and an adjustable idle airbleed under the triangular whasher.
Here is the factory recipe:

Thank you, Kenth!

This carb was on a '68 YE engine that I acquired several years ago, so I always assumed it was the original carb. Looks like the only deviation was the "J" hanger, as it turns out. 74 and 46(single taper) and BE's were all present.
