Our 66 Chevelle mule has been equipped with either Shockwaves or coil overs for quite a while.
We use a bolt-in bracket in the stock shock location so your exhaust and lower control arm mounted sway bar will still work. The upper mount is a bolt-in adapter that allows you to utilize the bearing mount of the shock.

I've also attached a quick image for reference.
