Unfortunately, the 25$ jegs universal didn’t fit, so i had to go with a metco m odel specific unit for 100$. Nothing much to report other than I had to take of the exhaust AGAIN. And I need to go buy some bigger washers since these just aren’t cutting it.
For those unfamiliar, I had a rear u joint “incident” where the driveshaft tried to enter the passenger compartment via the floor pan. Unfortunately, despite my best intentions the forward loop only really addresses the front s eats. I am still apprehensive about having passengers back there.
I am left needing to return this Jegs unit, and I had a thought: why not use part of it to reinforce my floor pan right in the problem area?
Would fit right in the tunnel. Need to widen the ends apart. But before I go ruining the return value: this is some kind of hardened steel. Can’t even bend it slightly by hand. Should I bother putting it in a vise and cranking on it? Will I just scratch the shit out of it? Will it even bend or would it snap?
Thanks guys!

How do you know it’s hardened?

If you have a torch you can heat it and release some of that pesky strength...
But, I wouldn’t ask a Torch.

Depends on how hard it is but it might just break. You could put some heat from a torch on it which should let it bend but not break.

I guess it is just some special high carbon steel, but it is to prevent driveshafts from flying free so its pretty beefy stuff.

Would just a regular propane torch do?

Typical annealing temperatures (500-700 degrees) can be reached with a propane torch, I think.

“Universal” doesn’t fit a 2nd-gen F-body?

Lol. A36 is just regular low carbon mild steel. It’s ductile (which is good - you want it to plastically deform to absorb as much energy as possible).
Bend it in a vise. Warm it with a torch if you like. It’ll be fine.

I’m going to be pedantic here, so forgive me in advance...
The material hardness doesn’t impact whether or not you can deform it with a given force. All steel has approximately the same modulus of elasticity, so a given force deforms them all the same, if it doesn’t break it. Now, hardness often goes with higher strength, so it may take more deformation, and thus force, to break or permanently deform it because it’s hardened. (Or not - depends on a lot of details.)
Ok so that said..... the hardness may mean you just break it in the vice instead of deforming it. (Oh and you may have trouble getting vice teeth to grab if it’s really hard.)
Heating will both anneal - as suggested elsewhere - making the material softer and weaker and, for temps above 700ish F, will really start to lower the modulus, making the steel easier to bend.
TL/DR: Hit it with the flame axe!

Sounds exhausting.

How much do you need to bend it? If it’s brittle enough you can’t get an inch out of the ends of the U than it’s not going to do much good against the shock loading of a flailing driveshaft.
Short answer: it should be find to bend; if you’re too worried put some heat in it but know that wherever you heat it the most will be the softest point most likely.

This. A36 is garbage generic low carbon structural steel. The only way to harden it is case hardening, which this ain’t. Can’t bend it by hand? Use a hammer.

Actually started bending it with a floor jack lol

Yeah tell me about it. Not without serious modifications anyhow.

Puns aside I am so over working on this car.

If it's hardened then it will just snap.

You could always take my approach and just not do anything to it for 3 years. I'll have my van 3 years next month.

It will have been a 5 year haul just to get mine inspected.

Sounds like you'r
