A friend of mine a couple of years ago had a 69 or a 70 and put new style Escalade headlamps on it and a custom grille. It did not look that bad. I dont know if he still has it, but I'm with everyone else, why ruin that front end?
you think its ugly, dude he drives it daily n hes using 2x3 tubing currently for his frame n it will uglier than the whole truck and it wont last long not cause he drag cause it will crack n bend with the lack of support
