It’ll hand like a dog with such a short stem, and the range of quill stems available isn’t huge so you’d probably be looking on ebay.
With older frames, frame size was much more critical than on modern frames where spacers, stems and seat posts can be used to make it fit a wider range of riders. Unless you’re 6’2+, I’d ditch the frame (they can make handy money on ebay) and get something that fits.
Are you looking to use it as a winter bike? I put the bits off an old Ribble on a Dolan Prefissio with full mudguards… It’s fantastic.
