I would, without a doubt, put a Campy Super Record crankset on that. They belong together. I'm not a stickler to using vintage parts, but some do have their place in my book. I wouldn't even consider brifters. I would use DT shifters - Campy if I could find them without spending too, too much. I just swapped out my 1" quill stem for a converter and a 1 - 1/8" inch stem and modern dropbars - on an '82 Puch A-D Reynolds 531 everything. So make it your bike. But Campy SR would go on it if it were mine.
