need advice attaching a small bioPace chainring

Retro Newbie
cross-posted from Road Wanted; hope that's ok.

I acquired an '85 cannondale st400 and i'm setting it up as a sturdy touring bike.
Previous owner had removed (and discarded) the small chainring from the triple-crank, and I need some climbing gears (48/44 atm).
I found a compatible 28t granny on ebay, but am just now realizing that the spacers and bolts are non-standard?
Any suggestion on where i can find them??

here's the bike if that helps... https://www.facebook.com/marketplace/it ... 1704196922

Is this what I should be looking for? https://www.bikeforums.net/bicycle-mech ... acers.html

THANKS!
