I recently purchased a 86 blazer rear bumper on ebay. I was planning on putting it on my 85 pickup. I recieved the bumper today and it a has the same shape as a 73-80 rear bumper but the bolt holes are not in line with each other like my 78 blazer. I have brackets that I got from gocartergo that are from an 80's blazer. I tried these and brackets and they don't line up with the bolt holes on the bumper. The bolt holes on these brackets also seem to be directly over each other, just like the 78 bumper and brackets. What do I have? It appears that all blazer bumpers have the holes directly above and below each other and my bumper has the holes offset with each other. Is there any difference between the blazer and suburban bumpers? I thought they were the same. Please help as I am trying to decide wether or not to email the seller and tell him that i'm not satisfied or just build brackets. I would at least like to know what it is off of. Thanks in advance! baldbandit "Have you driven over a F@RD lately!!
