Had a fan shroud break in my dad's 1978 Chevy silverado with a/c. The part number on the shroud is 470906-1. Its the top piece. I ordered a new one from npd and it doesn't match. Its too short. Theres a version of it thats heavy duty cooling and one's thats not. If anyone knows what the difference is or where I can get a fan shroud please let me know. Thanks
