Aftermarket steel frame cab brackets

[TrexMex]

So I stumped into these frame brackets on eBay:

My rear of cab frame brackets have been pretty much eaten away by rust and right now the cab sits 1" higher on the driver's side since the passenger's side bracket has already failed, so I decided to give them a shot. If you take a look at the pic the corners where the bends meet seem like they are welded; well, they're not. I was wondering if they should since my understanding is that that would actually put that bend to "work" under stress with the rest of the structure and not just take all the load by itself... I can do the weld myself, I just don't want to mess up the design if it is supposed to be like this...

Hope someone can help me...

From the pic, they don't look that beefy, you could probably make a better set yourself cheaper. If you already have them, yes, I would weld the seams together.

Thanks for the advice, I already have them. The plate looks like the same grade the originals were made of, I guess the "beefier" part comes on the bigger support. I would've made the top smaller though to transfer more of the weight to the support. I was thinking on replacing the rivets with grade 8 stainless bolts, but still haven't decided. Any idea on the torque that I should apply to the bolts?

Thanks again for the advice.

BTW, I meant the rivets that attach the bracket to the beam.

umm... stainless and grade 8 are not one in the same. its one or the other. you will want grade 8 half inch bolts.

What do you think the holding strength of the factory-installed rivet is? I hardly think it matters between Gr. 5 and Gr. 8 for a body mount bolt. If it were me, I'd probably weld it on.

Just a quick 2 questions about body mount brackets... sorry I'm new here. First is I've been looking for replacement body mount brackets for the cab of my 92 Ranger Extended Cab online and the few sites that I have seen say that the rear cab mount they offer won't fit the Super (extended cab trucks) Why is this? And where can I get new brackets? Is there anyone else after market etc.... Selling them? Thanks for any help folks.
