They're not exactly the same. One is an older model without all transmission hole applications. $175 Scattershield has had bolts welded in for easier installation for the trans. Both will fit Muncie Saginaw t10 and super t10. I paid less for the $175 Scattershield then I did for the $250 one. Just trying to get back what I paid. Neither has sfi certification stickers. I'm looking at saving my legs not meeting sfi requirements.
