Take those parts numbers to a Chevy dealer's parts department.  They're likely obsolete and unavailable.  What the parts guy can do if he wants to be helpful is use their national database all Chevy dealers are connected to and see if any dealers elsewhere in the country might have any of those parts on a shelf gathering dust.  

You can contact those dealers that have the parts...they may well be willing to sell you the parts cheap just to get such dead items out of inventory.  I've done that...it doesn't always work but sometimes it does.

ANY GM dealer can cross-reference any GM part number these days. I can get Cadillac parts from the Chevy dealer, if I want. Finding a parts person at the dealership that's willing to LOOK is the problem. Unhappy

Very true Joel. 

Similar scenario pertaining to a parts search...
Fortunately I have a good parts parts guy at the local Chevy dealership.
A few weeks ago I was looking for a original hood release cable with the tee handle and bracket for the '81. P/N 14030127. Fits only '80-'82's. 

The guy tells me the number is no good, then says it's discontinued. So I asked if he could do a dealer network search. Bingo! There was one on a shelf and at McFarland Chevy in Kentucky. So I now have that original cable assembly vintage 1981 with about 2 inches of dust on the box awaiting installation. Thumbs Up

So see if your parts guy can do a search of all the GM dealers in the U.S for you. You never know what could turn up.

Here is a Quadrajet carb decoder for everyone, that I found in my search for the carb parts I was looking for !!

Rochester Number decoding

Example: # 7028219
               DG 1938

These numbers can be found on the side of the carb main body next to the throttle lever , 1965 to early 1968 was a round disc 1968 and later ones where stamped into the body on quadrajets


If the date code under the number is 4 numbers "1938" like above it was produced by Rochester
If it looks like "A8 o MM" then it was produced by Carter ,Carter produced millions of quadrajets with original numbers under license from GM. Carter also
 produced carburetors with O.E. calibrations with the Carter numbering system, which is 4 numbers followed by the letter S on the quadrajets

7028219

Prefix code. "70" will appear on all late '60's Rochester Carburetors.
      76 and later will start with "170"
      2 - Decade produced.
          702 - 1960's
          703 - 1060's with A.I.R.
          704 - 1970-1975
          1705 - 1976-1979 
          1708 - 1980's 

7028219

Year produced.
     8 = 1968
If the number was 7045219 then
     5 = 1975
7028219Model
     0 - Monojet (1 bbl) Federal standards
     1 - Two jet (2 bbl) Federal standards
     2 - Quadrajet (4 bbl) Federal standards
     3 - Monojet (1 bbl) California standards
     4 - Two jet (2 bbl) California standards
     5 - Quadrajet (4 bbl) California standards
     6 - VariJet (2 bbl) Fed
7028219  - Division.
     0, 1, and 2 all indicate Chevrolet.
     4 - Buick
     5 - Olds
     6,7 - Pontiac
7028219 - Transmission most cases
     Even numbers - Automatic Transmission
     Odd numbers - Manual Transmission
DGProduction Code.
1938  Rochester produced carburetor Date Code
     193 = 193 rd Day of the year
1938   8 = Year 1968
Other
