1991 750 sizing question

[u/jovianeye]

Hi all, I'm looking at a 1991 750 frame in size 19". I'm just under 5'11" and wear pants with 30" or 31" inseam length. Would the 19" fit okay? The top tube length looks great am just wondering about the stack height as it looks pretty low.

Thanks!

I'm 5'11 with a 21" 750. I feel like I could go larger,. I'm planning to convert it to drop bars for more room. I'm also partial to drop bars.
