Ok, so got it out. I think the pictures below explain it all. I think my repair job will hold up just fine, let me know what you think.

I think this is supposed to be attached.

Everyone knows black duct tape is superior to the standard silver tape, so I think I got this covered.

Best part about it, it blends right in, so I don't even have to repaint!

Nice job, Mick! Personally, I would have used a generous bead of super glue prior to applying the duct tape. But that might be overkill...

is there something weird going on with your LCA pivot tube? the weld looks strange.

Yes, I noticed that as well. We will be going over the whole k frame, looking for any other issues, so I'll definitely take a closer look at that.

Yeah, I think so. The engine only puts out 700hp, duct tape should handle that! up

But seriously folks, ee are going to repair it. It is truly amazing, just how bad these welds were from the factory and that it lasted this long. I thought about which way to go, and with the above fact, terrible welds and still it lasting as long as it did, I don't have any doubts that welded properly it will be good from here on out. We are going to go over the rest of the k frame and redo welds that don't look good as well.

From what I can tell the welder missed most of the mount perch. I picked up an A-body k-member where they forgot to weld in one of the strut rod reinforcement plates. The body of the k-member cracked behind it.

I've seen messed up control arm tubes before, they can be tricky to weld.

The last few k-members that I have done I have cut the bottom open below the pin tubes and welded from the inside. Might also make sense to open the top and weld it from the top, too.

I'm hoping it doesn't come to that. If so, may be worth just finding another one. I'm hoping to have it back from the powder coating guys, (burning the old stuff off), soon, and then we can really go over it.

I do it as a preventative measure. I'm not sure about your k-member, but the tubes did not receive much of a weld on one end on A-bodies. Here's a pic. I actually split this K-member so that I could straighten it. In part just to see if I could...

That car is a beast! Does it already have subframe connectors in it and the front frame rails tied together?

I have the US Cartool connectors, the ones that are welded all along the bottom of the floorpan. It makes a big difference!

So, here is the latest. The K frame is all welded up and ready to go. We tacked the perch on, and then I did a test fit, and it was perfect, so we finished off the welding.

I decided to stick with this (instead of going for a MegaParts hemi K frame, I have the Schumacher mounts), for the following reason. When you look at the photos, you will see how ungodly horrific the welds that held this perch on were. It's absolutely astonishing to me that as bad as these welds were, that the thing lasted this long. The welds along the seams that make the perch itself are very, very nice welds, so no worry at all there. When you compare what was there before, and what is there now, I have full confidence that it will outlive me!

I also put the FirmFeel braces on the LCA's, a few pictures of those.

We also reinforced a number of other areas on the K frame. Some welds I ground away and we redid, and some we just added in places that can only help. Pictures should say everything.

IMG_4889.jpg
This is where the perch was welded on the top. You can see that the weld barely penetrated the metal of the perch.

IMG_4890.jpg
This is along the side. Again, astonishing these held as long as they did.

More pics:

The top of the steering box mount. This is from the factory, (minus my cleaning it up).

IMG_4913.jpg
Whoops! A split in the metal. Don't know if that has been there, or was caused by the latest incident.

WOW, some of those factory welds look like my doing!

But, I swear, I was nowhere near the the factory back then, Iowa at the time, in college.

Sooo, my welds WOULD have looked like that ...


It takes gasoline to interest me.

It is scary how bad some of them were. Especially that perch. The guy knew that this was holding the engine in place, but hey, good enough, I guess...

I didn't show any pictures of the before on some of the others, but pretty bad. Hard to believe someone was hired with that lack of a skillset.

I've seen more sloppy welds on k-members than on about anything else.
