Just as a reference (for anybody searching), when i was buying wheel studs, i found that NICE manufactured and sold a good range of lengths for replacement studs for 1000, 1200 and 120Y hubs (They didn't specify 1000, 1200 or 120Y in the catalogue but the dimensions were spot on and they fit). I can't remember the part numbers but Repco and Wolfies were the 2 part shops that stocked them (ordering was a 4 week wait).
