Louis,
always willing to learn, but I don't understand what you're saying. When I would add two tubes the way I think you say, that would not help at all.
The LSV is sitting against the right frame rail with bolts. Four that is, but that doesn't matter.
If I would place the LSV on two (or four in my case I think) studs, all it would do is move the LSV away from the rail but parallel to the axle. So to mmy opinion that wouldn't alter anything in regard to the way it is 'steered' by the axle moving up and down.
On the picture you can see the LSV sitting against the RH rail. Photo is taken from a point near the attachpoint to the axle (Arrow).
Extending this point upward - instead of bending the rod is no option either. The extension would pierce or at least hit the body floor with the axle in most upward position.

That's why I've bend the rod and I can assure it's working as it supposed to. Had the annual inspection about a month ago and no complaints but that was no surprise as I've done this bending several years ago and the pads are wearing evenly and towing a heavy load is no issue as well.
So I assume the 77 has a fully different setup or I'm misunderstanding what you wrote.
