Re: is this the correct part number for l69 carb???
Probably the easiest way to tell is whether it has DR Rods on a F hanger from the factory. Hangers are stamped right on top w/ letters ranging from B to V and rods are stamped w/ 2 letters.

Re: is this the correct part number for l69 carb???
Here are the part #'s on L69 Q-jets-
83: 17083205
84: 17084205 M/T, 17084208 A/T
85: 17085203
86: 17086040
17059182 is not in the factory GM F-body parts catalog, I have the standard catalog of Chevy casting #s which has all the Rochester carbs 55-88, and 17059182 is not listed. There are a bunch of 1705XXX Q-jets used on '79 model Chevys, especially trucks.
Re: is this the correct part number for l69 carb???

Re: is this the correct part number for l69 carb???
five7 good eye. there is a vacume tube coming out of the front of the carb. it goes to a dual plug right by the thermostate housing but is taped over.? the two wires coming from the carb are not wired to anything. did not look might have come off somwhere. the 87 trans am had center bolt valve covers. in canada maybe my car did not come with air pump. i know my 85 trans am never came with an air pump. what does the check engine light look like? i dont think i have that. here are a bunch of pics i hope someone can help out.

Re: is this the correct part number for l69 carb???

Re: is this the correct part number for l69 carb???
i live in canada and its a canadian car. i dont think my car has a computer . it does not have the plug on the carb. what is the light supposed to look like on the dash for the computer?
Did you just update your user info? I don't recall anything about Canada except what I said.
The carb you have on the car is the correct one. The CC carb is no good to you.
The connector on your current carb is supposed to go to a thermal switch on the thermostat housing, which obviously has been removed. It doesn't really affect the overall operation of the carb except to give you a full accelerator pump shot all the time.
