Singlespeed & Fixed Gear - BB spindle length for old school Sugino road cranks?

Just curious if anyone knows offhand. I think my bike currently has a 110 and the cranks bottom out on the shell and chainstay. Cranks are a Sugino GT, set up as a triple but really a double with some spacers and an extra ring.

i had a sugino double road crank on my fuji before i converted it. i'm pretty sure it's a 110mm spindle, cause the shop i took it to thought it was a 109 and it's definitly not a 109.
Hm, maybe I have a 107, then. Shows how long since I removed that BB.

I had a set of Sugino VPs that I think took 110.

If it's a triple crank it'll probably be much longer, like a 117.

I run Sugino ALP cranks and Sugino GLP cranks on my other bike. Both require a 113mm spindle to get the right chainline with the chainring on the inside of the spider.
Well, I played with it today and I can't figure it out. 122.5 is just a bit wide with the chainring mounted outboard. 113+118 were too narrow. I gave up and just kept using my old Sakae cranks with their perfect chainline and low Q-Factor. Thanks for the input though.
