Sport rear bumper interchangability

[adaml23]

Hey guys,

So this weekend is LKQpickapart's 50% off everything sale and was gonna go look for a few things. The main thing is a rear bumper (and brackets). The yard up here has two squares but neither one has the sport, they have the step bumpers. I was just gonna possibly grab one of them but then I remembered someone saying the suburbans can have the same bumper. Well, unfortunately the only square burb they have isn't what I'm looking for.

But then I thought about the old G20 vans.... And they do have a few of those up there. The bumpers look pretty similar (possibly identical) in the picture. So does anyone know if those are the same sport bumpers and brackets our trucks use or are they different? If they are different, how much different and are the brackets at least the same? I could possibly reuse my old bumper but the brackets for them are shot/partially missing.

Any help would be greatly appreciated before this weekend's trip up there!

No those are completely different bumpers. The square body fleetside rear sport bumper wraps around the sides very similar to the front bumper.

The G20 bumper does look an awful lot like the stepside short box rear bumper though

I don't suppose you know if the brackets are totally different then too?

No idea

The van bumpers are the same as '73-'80 truck bumpers EXCEPT for one very important detail. The bolt holes are in completely different locations. And the brackets are nothing the same.
