first you'll have to know if yo have tbi or mfi on the vehicle. you could go to a salvage yard and pick one up if they have one or you could try a tbi unit from like a cavalier if it's tbi as i think they are the same as GM sold both of those.

it's a tbi unit. then go to a junk yard and see if either a cavalier that has a tbi unit has tht or another tracker. i'm sure they will let you go back and find one.

no if you go to the junkyard get just the screw if they have a unit that is scrap anyhow they will more than likely give it to you.
