I didn't even lay a magnet on the bracket to see whether it's steel or not, but the upper bend is reinforced with a fillet. I can't see behind the lower bend, but that would be where the bending is intended. If the bracket are really that soft, the bending could be accomplished with a light-to-medium tap with a hammer.
I like the idea of shimming. It wouldn't take much (maybe 1/28" maple veneer) given the leverage. No room for feeler gages with the damper wires in place, but I can used numbered drills to get within a few mils of the proper thickness. I'm in on this piano for a couple of days of action reconditioning/regulating/voicing, which doesn't necessarily involve any complete dismounting of such a system (if the brackets have to be in a machinist vice for bending). But the damper timing is early, and (because the work is going well), if the damper posts slip nicely on the wires, I might throw all of this in as well.
Thanks for the suggestions. I like it when there's a single clear answer: that means its the right one.

It looks like a choice between bending the bracket (which should be doable) or loosening the screw and inserting shims as needed.

I'd like to regulate this sostenuto, but it shows no sign of being adjustable. The sost blade need to go another 2mm under the tabs (and they themselves need to be leveled). My best idea is loosening the mount onto the belly rail on sticking a paper clip on the locator nail on top, hoping to lean the blade below, inwards. I have no idea where the trapwork gets limited/adjusted.
I hope I'm not looking at a "set'n'forget" installation.
TIA
