Hi ! everyone, I am really confused trying to find the right shroud for my truck. I have a 1975 F-250 4X4 High Boy with a 390 motor, my radiator core measures 24 1/4H X 26 3/8W X 1 7/8 depth. I called to order one from *** Truck, the one they offer is for a truck with A/C, mine does not have A/C, will this shroud fit on mine? On my truck the mounting holes for the shroud the shroud has 4 holes on the passenger side and 3 holes on the driver side. I hope some one can help me with this problem, thank you for your time and help!!! 390man
