Hello from Tampa

The idler pulley did not come with the kit but it fits and lines up with the A/C pulley perfectly. It was pulled from some small block Mopar from the junk yard . I don't remember what make or model . I removed the pulley and there aren't any part number stamped on it. The only stamping is " D24 " with the letter D turned 90* to the left. I hope this helps.
Appreciate you taking the time to look.
