cooling issues?

[Delta Boi]

Well i wrecked my baby last year..minor body damage but it ended up wit cooling problems. I've changed radiator, theromstat, fan, fan clutch, hoses, and had pressure checks doneto the block for leaks. Nothing seems to help keep it from overheating after a few hours of driving. If anyone has any advice or can inform me of any parts that i may have missed during my search for the right issue please send info. Also if anyone knows a site i may be able to order new front grill and front bumper from let me know. I found a place for all trim pieces so just let me know something. Thanx
