i came across a set of nerf bars for my 1976 blazer. the guy i bought them from said "AH, THEY WILL FIT ANY BLAZER". well, they dont. i believe they are for an 1987. anybody got any tips on how i can fab'em to fit a 1976? they have brackets on them that bolt to the frame. what ever i got to do to make them work, i'll do it. i am going to end up herculining them anyways.
