Default Best ideas for front upper 'A' Arm stops for 68 GTO

Does anyone have a very proven simple way of installing adjustable stops for front upper 'A' arms for 68-72 A body GTOs, when you are pulling the wheels?
This is for a street driven and strip raced full bodied GTO. I am hoping to pull the wheels up about 1ft to about 2ft on launch at the strip with a stick transmission.
Thanks in advance for any proven advice and or pictures.

I'll take pics of what I did to my 67. I welded a huge nut to the top of the UCA, and threaded a bolt thru that. The bolt hits the bump stop during full extension. I added a second nut to lock the bolt where I wanted it.

Keep in mind that the purpose of the stop is to keep the car from hanging the hoops 2 feet in the first place.

For sure! Goal is to go forward not up!

Did same mod but just used 3/4" threaded rod and cut a screwdriver slot on end of rod with a cut-off wheel. (1/2" to 5/8" would probably work fine I had the rod and nuts from another project)

1/2-13 stainless nut TIG welded to the A-arm, 1/2-13 stainless bolt with a large flat washer welded to the head of the bolt so the rubber bumper has something flat to bump against. I cut a screwdriver slot in the end of the bolt so you can make adjustments from the top, another 1/2-13 nut locks the adjustment.
