  I'm not sure where you can find that page you're looking for, but I did a search online and got this:

The Rochester Quadrajet carburetor with part number 17088152 is an electronic feedback (E4ME) unit. It was a factory-installed carburetor on various General Motors vehicles with 5.0L (305 cubic inch) V8 engines in the mid-to-late 1980s. 

Specific models it fits include:

Buick: Regal (1986)Chevrolet:Camaro (1986-1987)Caprice (1986-1988)El Camino (1986-1987)Monte Carlo (1986-1988)GMC: Caballero (1986-1987)Pontiac:Bonneville (1986)Firebird (1986)Grand Prix (1986)Parisienne (1986) 

The number 17088152 is recognized as the last automotive Quadrajet number produced. This carburetor was designed for computer-controlled applications and required a 12-volt power source for its electric choke element. 

  Is this what you want?

Cadman-iac,

Thanks for your reply! To explain what I'm trying to do, sometime around May of this year my son and I started a project to identify all Qjets produced since 1965. At present we have identified in the neighborhood of 1270 different Qjet numbers with over 1900 different applications including some from Australia. In order to do this I purchased several Delco Rochester "9" Parts and Service manuals(aka the Big Book). They covered the range from before the Qjet in 1965 to 1989. These are directly from the manufacturer and as close as one can come to direct confirmation of the numbers/applications as I can do.
So I was looking for that elusive 1990 last application index sheet(it may not even exist) to finish my database.
I appreciate your insights into the usage of the 17088152 carb as It helps clarify my understanding of  it's application and it helped clarify that it was the highest numbered automotive Qjet used(not the last number used as I originally believed), that appears to be 17088115 or the highest numbered Qjet used 17089112 Mercruiser Marine.

Hope this helps.

P.S. I'm partial to Cadillac carbs. I'm running a modified 17057230 on my 1972 Super Cheyenne.

I wonder if they continued to produce marine carburetors after 1990? 

Kenth:
If you bought a new replacement Delco/Rochester Quadrajet for 1990-88 Buick, Cadillac, Chevrolet Oldsmobile or Pontiac you would have a 24-5092.
24-5092 is stamped 17111994 and it replaced 17088115.

Info from 1997 ACDelco Carburetion Catalog.

Kenth,

Thanks for the info, I don't have any catalogs or manuals past 1989.

novadude,

My best guess is Yes, if you mean for sale as a replacement carb. I see Marine carbs on ebay all the time with model numbers in the early 80's and Julian dated late 80's. But as I said I don't have any proof.
