does this fit a k1500 gmc? year 99

Compatibility chart says yes. Looks to be first year this model was used. From list -- 1999 GMC Sierra 1500 All- sub models All- engines Actual OE Part

why can't this item be shipped to me

Same problem add to cart but try different addresses in California says cannot ship to the address O_o

Does this have a temp sensor as described in the other acdelco 19330121 gm original equipment mass air flow sensor with intake air temperature sensor?

No it does not. This is only the mass air flow sensor.

The search and picture represent the part number of 25168491, but the number on the part received is 15904068, are these different parts?

Should be the same as they are both a af10043
