If the original HS on this Puch was a Dura Ace from 1976 (and no idea what "UA-100" means cause that does not align with Shimano-speak,
AFAIK!) then let's refer to Sutherlands again:
if your properly-fitting HS was say a DA HP-7100 then the stackheight was 39.7...if it was some other DA then might be a shorter SH but I don't see any in Sutherlands that are taller.
So once again: you probably could use a Tange Levin (SH 37.5) and add a 2mm spacer.
You should be 'golden'.
For fun .... I went on a little Dura-Ace fishing trip to see how the parts were labeled/categorized. Just like going fishing you never know what you catch. Inconsistency across the board is what I found. There is no definitive resource on all things Shimano, let alone Dura-Ace. Anyone claiming to "know it all", is only adding to the folly, even me writing this does ! The more I dig the more I found to dig for as the inconsistency only grew. So it goes with the hi-story of things, every time a story is told the plot expands
. I would have thought the original Dura-Ace boxes showed a model number, but not from the tops and sides of the brown boxes I've found photos of. That's not unexpected though as with an original model there often is no model number. It's all for fun !
