What type of torsion bar adjust bolt/block is this?

[Jonas_N]

The threads on mine was a little worn, so I bought a new set from member VegasCharger here on the forum.
I asked for bolt/block for a -68.

The ones I got sent to me has a wider block (Doesnt fit in my LCAs), longer bolt with different thread.
In the pic my old one is to the left.

So the ones I got, what LCA do they fit?   (Did the 68 come with different LCAs?)

72-79 model maybe. They did have wider lower arms.

Well, i didnt specify what year in my wanted add...money in the lake.

The "big" one on the right is for the "C" body line of cars.

Nope.
All 62-72 LCA's are all the same thing.
Only difference would be where sway bar tabs would be welded onto the arm.
66-69
70-72
