If you think your situation is a pain, you should have experienced mine!
The tubular lower control arms I got from Global West JUST HAVE HOLES (no threads) for the lower shock mounting. The metal is much too thick for j-nuts.
I ended up putting long bolts up from the bottom (fighting gravity) and reached through the spring coils to start a nut. I then tried reaching the upper nuts through the frame and coils with 1) a long extension and u-joint (not), 2) crows foot wrench from below (close) and finally, 3) an open ended wrench suspended into the middle of the spring coil with a string and then held in place with Vise Grips slipped between a spring coil that was wedged open with a block of wood.
Those new Edelbrock IAS shocks better be fantastic because they are NEVER going to be replaced!
