Default optional rear anti-sway bar attachment

I have an '89 Caprice with the F41 sport suspension option. Included in this 'package' is a REAR anti-sway bar. It is described via an 'exploded' diagram in the GM shop manual, on page 3D-7, figure 9, entitled "stabilizer shaft". A "bracket" is used to attach the stabilizer bar to the lower control arm in the rear, on each side of the car. The GM shop manual diagram number is: KC1009-3D-B-RP.

My latest acquisition endured some New England Winters... and the "bracket", a thinner-metal stamping, has rusted away.... and my anti-sway bar has become detached at one end. The anti-sway bar itself is just fine: no damage. I need at least one, preferably two, replacement 'brackets'.

The problem is most "old Chevy" parts dealers are all performance-oriented. They're not likely to have such an item. I would like to have the GM part number for this bracket, but don't know where to get it.

I figure that I need to find a junkyard / salvage yard.. in a relatively low-rust area... that has an old Caprice with said anti-sway bar... so I can buy a replacement bracket or two. This is not easy, given that most "junkies" have long since crushed anything near the age of my 1989 Caprice.

Ideas? Suggestions?

First off I'd look at the specialty vendors who like the Impala SS.

Stock / base-model lower control arms are stamped steel and
can't stand off the crush force of the sway bar bolts unless you
put an insert. This could be a couple chunks of scrap aluminum
of proper thickness and two holes apiece. Or a couple bits of
1/2" iron pipe with maybe fender washers to taper out the load.

Boxing the arms could firm things up but you need the internal
reinforcement.
