Okay need some help from the collective and Old Hands here.
I recently bought this '88 4Runner for parts.
See attached link - is anything here (aside from shock) NOT standard?

WARNING - large file (hi res) - did that to increase viewability...
It sits pretty high, about 3+" above my '89 which has stock suspension and 1" smaller tires. After some probing, the seller said it had a "torsion upgrade kit" but he wasn't sure what that was or meant, that what the PO told him. He just bought it, drove to a shop and had the engine extracted. And for that reason I don't know how it rides either.
But I don't really trust what he says/knows, seeing as he also said the PO told him it had AALs or helper springs in the back... and it dosn't, it has 3" blocks...

You can see how much droop there is in the pic - but note it's supported by the knuckle so this is compressed/loaded.
I've measured only about 1-1.5" difference in tire-to-fender distance w/ it loaded weight on wheel vs jacked on frame, which seems like very little.
My suspicion is, the T-bars ahave been cranked to all hell - but can you get that much just by that alone?
Don't have a caliper on hand (yet), but dirty measurement is that t-bars are about 1-1/6" diameter. Is this stock?
