Rear bumper brackets

[SeanPaintsFlames]

If they're all being replaced, wouldn't these brackets (for a 73-80) work on an 81-87? The new plain ol' chrome bumper we're using is labeled for a 73-87. I don't get the differences. I can't find a brackets/bolts kit for the 81-87.

73-80 bumpers are shaped different than the 81-87 bumpers.
The brackets are also different.

I am also looking for rear bumper brackets for my 86 stepside... Will the 81-87 brackets be for the regular small bumper and not the huge one.. Can someone help if they know what I am talking about.... Do the brackets have to be from a 81-87 step or fleet..

No they wont fit, stepside bumper brackets are different that sport bumpers and they are the same from 73-87 unlike fleetside bumpers. Note Ill#17 below

The 73-87 STEPSIDE bumpers, are actually the same bumper as the 67-72 stepsides have,... but the 73-87 trucks use a different bracket set-up.

They rear sport bumper brakets break down as follows:
Stepside
73-87

Fleetside
73-80
81-87

That's the bumper I am wanting to get... So any 73-87 stepside brackets would fit that bumper?

Yes.
Find a set of 73-87 STEPSIDE brackets,... and then buy a 67-72 rear stepside bumper,... and you will have the correct rear bumper for a 73-87 stepside.

Here is a set of 73-87 stepside rear brackets.

In that LMC page, bumpers 1 and 2 have the same looking holes or brackets. We have bumper 1, the smoothest of them. I think that the bracket kits may be interchangeable between the fleetsides as long as they are together. It looks like the 80's trucks used stubby inner brackets instead of the 4 long ones that sandwiched the frame. Anyone have pics of the rear frame of the 70's trucks vs the 80's? Is there a rear crossmember difference or anything? I'd look at my 83 but it's a crazy drop bumper with globs of welds instead of legit bumper brackets.

The LMC pages shows that the fleetside brackets are different.
They all sandwich the frame.
Look at parts 18, 19, 20, and 21.

73-80 or 81-87.

You can see it in this picture, the end that attatches to the bumper is stepped for the 81-87 fleetside. I just bought a set of them from choicebumper on eBay, but they don't have any more listed. I think a few of the vendors on here sell them.
