They are for 22.2mm stems of the quill type so you'd need a threaded headset. if you have a 1&1/8th threaded headset you could use a 1"(22.2mm) stem with a shim which I can also supply. For simplicity a single ringed front chainset and 5-7 rear cogs so the single powershifter be fine or if you want versatility of double or triple then the twin lever versioned be better.
The Kens right though if your planning to ride off road like you normally do on an mtb but if its the drop bar look and you plan a much reduced pace then stem shifters should be fine. Alternatively I also have a set of NOS Suntour bar end shifters, 21 speed surplus to requirements.
Just had another thought having now seen the bike, what is the diameter of the stem as regards the forward reach part. You could possibly shim a band on shifter into place as its quite long. Again I can easily source loads of band on downtube shifters.
I have also seen rapid fires bodged onto the ends of bar ends with tubing slid inside the drop bar ends and secured then the new tube shimed to 22.2mm.
