What Grass Bagger for Simplicity Broadmoor

I just bought a Simplicity Broadmoor 16LTH (model no 1692106), either late 1990s or early 2000s. It has Hydro trans and 38" mower deck.

I want to mount a grass / leaf bagger but local Simplicity dealer says the bagger is no longer available. It was model 1694308.

Is there a bagger that will mount on my tractor? It does have the side shoulder bolts with possible high and low positions, but there are no holes in the back frame plate - only the filler port for the hydro trans.

The mower deck has the "swing-away" bracket for a turbo.

Thanks for any guidance.
