Hello,
Another oldster here who has a few years on you. Check out the pix posted by “noobinsf” & “Thumpism”. When building or rebuilding bikes, I often use threadless adapters. They enable me to tryout various stem lengths as well as different angles of rise or drop fairly easily.
If you have a co-op near you, check out their selection of used riser quill stems. This will give you some economical options. Personally, like to use riser stems to get more upright than messing with the bars.
Cheers,
Van
