Dan Fahey- if you still have the bracket or a drawing you designed I would love to see it. 2" -2.5" is about right for setting that upper control arm at parallel. Also, I have do have brackets welded in support the upper control arm mounting frame cross-brace.

Sheesh !!
The part is long lost.

Can Tell you how I did it.
Cut out several pieces of Cardboard.
Removed the Rear Bolt and raised the Control Arm about 2.5 inches.
Rules it had to be a Bolt On fixture.

Outside piece.
Cut two pieces of Card Board and taped them together.
Inside piece was the width of the Bushing.
That was for the out side of the Bracket.
Cut another piece for Inside Bracket.
Both inner and outer pieces matched the curve of the axle.

They were welded together to fit over the each side of the Bracket.
Cut another piece that curved around the axle.
Welded to the two inside Brackets pieces.

Intent was to use two grade 8 bolts for each bracket using existing hole.
Bolt Pinched the two plates to each side of the bracket.
Curved piece that wrapped the Axle would prevent the Control Arm Bracket from moving on Launch.

I then got my drafting board the made a drawing.
Worked with a Welder Friend also helped with the measurements.
For some reason did not follow my directions and went back forth until he got it right.
Then we had to move to Florida and never installed them other than for fitment.

Thanks. I have a set, but you can't use the lower hole with stock control arms. My stock control arms are boxed, however I might switch to adjustable solid arms in the future.
