Stronglight 99 and TA Pro 5 (50.4mm BCD) are both options, but both may require proprietary pullers (N.B. Stronglight cranks after 1982 use standard 22mm pullers, and there was a Sakae Ringyo 86mm BCD crank that used a standard puller as well. And there were other cranks, like the Sugino PX that used the 50.4mm BCD and a standard puller, but these are fairly uncommon).
