That's Kevin Manley. Recently he had a set on Ebay for $4500.
There's a bunch of parts that were changed, the shock tower itself, the apron around the top of the shock tower which allows the tower to recess outward, a unique outside shock brace, and then the shotgun brace that goes back to the firewall/cowl. Of course all the pieces except the shock tower itself is left or right handed.
The price does not include the unique export brace which another vendor sells for $950.
The upper arms are largely stock except they are notched at the pivot end to clear the shock tower.
Lower arms were moved out 1/2" on each side.
