Getting some measurements would help, much appreciated!

I don't know if it's the sport bumper. It looks like the one in this picture (not my ride).

On a Blazer/Jimmy the frame itself is the mount for the inside bumper bolts. It turns down and is the shape of the bumper. The outside bolts are brackets that go from the frame diagonally out to the outside holes. On a pickup, the rails are straight and all of the brackets bolt on to the frame. So if the ends of your frame rails are chopped off, you will need to scratch mount some inner mounts but you may be able to use the angled outside mounts to help position the sport bumper.

71's are chopped off like a truck, 72 is the only year the frame rail extends to the bumper.

71's take 4 bumper brackets 2 inners and 2 others. 72's only need the 2 outers.

True, the frame doesn't extend to the bumper. I thought only the non-angled bracket was used for the Blazer? I have all 4, the angled ones didn't line up with any holes on the frame.

Anyone have a picture of their Blazer's bumper connections?

Ahhh. Didn't know that. I've had 4 different trucks, 3 Jimmy's and a Blazer. Coincidentally they were all '72. Suprising they made that change but good to know.

Thanks for that info, thought mine looked different.

Can anyone with a '71 or similar help me out with a measurement or 2?

Just want to know where to set the bumper on my Blazer.

I have a 71 frame but no bumper brackets so I can get you a measurement of where the holes should be to mount the brackets. I'll measure from the end of the frame rail if that will work.
