hi I have a grill guard for a truck, it has a 7" opening to mount to front bumper. Within that 7" is a 4.5 curvature which mates perfectly to a 1/2 ton truck front bumper. Someone said it won't fit on a 1/2 ton truck, or suburban or panel truck, that it fits only large trucks 2-3 ton. Anyone who might can help, if you will email me at wwhitfield@triad.rr.com If it is only for larger trucks, will it fit a one or 1 1/2 ton truck, or it it only for 2 and 3 ton trucks? I can email you a photo. thankyou for your time.
