I'm going to use the SR Apex triple crank. It's a copy of the stronglight 99 and both can be run as a double or as a triple. It has an 86 bcd and new chainrings are still available via SPA cycles in the UK (which will ship to the US).
I think the SR Apex is underrated. It is a very pretty and versatile crank. I'll be running 48/38/28 rings.
Because the crank uses the same chainring bolt for all three rings, the bolts are long. I was surprised--happily--that you can get long sugino bolts (14 mm) from Amazon and they work on this crank.
It's always hit or miss when looking for a bottom bracket for an old crank but I tracked down an SR catalog via the web. It has all the technical info you need. The SR Apex takes a D3SS which is 121.5 in length. I had a shimano D3SS in my parts bin and a set of shimano cups so I'm good with the BB. Actually having the right spindle and cups in your parts bin counts as good luck for sure,
