Early A Body Sway Bars

The best sway bars, front and rear, by far are made by Firm Feel:

Anyone here have experience with a Firm Feel rear sway bar? The brackets that mount to the fram rails are bolted down with sheet metal bolts. Does this hold up overtime? Does this give a solid mount? I would think a lot better design would be to put a sleeve through the framerail and run a bolt to squeeze the bracket from both sides...like how Hellwig mounts their link bolt.

Anyhoe, I guess if it doesn't feel good I'll weld the bracket to the frame - I'll probably get to this anyhow. Then I believe the Firm Feel would be the superior design.
