As far as I know, there is no mod that brings stadimeter back to MaGui F's UZO.
You can use the methods Tupolev told or use my mast/range chart from Charts addon 1.4. You can download the mod from Subsim's SH3 Graphics download section and edit the chart as a slideout to your UZO or print the tga with the mast/range chart.
