Trying to find what this carburetor fits...

I have a Delco Carburetor that was givin to me. The part number is 17111329. Alternate code is 24-8015. GR.3.725. I was told it is rare, but no idea what it's for. Can anyone here help? Thanks

How about this?

That looks like an electronically-controlled Quadra-Jet carb. The basic carb design is very common. Literally millions of them were made over the years. There were countless variations made for all kinds of different applications, from small cars like the Chevy Monza up to medium sized trucks.

This particular application is for a mid-80's Dodge truck. I guess that's kind of rare - GM parts used in a Chrysler product. However, rare does not mean valuable, in this case.
