I decided to go with a 170mm FSA Tempo Tripple crank after finding a site that listed some info on it
Bolt Circle Diameter (BCD) The middle and outer ring are 130mm BCD, inner is 74mm.
BB spindle; Standard (JIS) Square Taper.
118mm produces the same chainline as Shimano 105/Ultegra triples.

I bought it from this seller which doesn't list much info but I asked him what the BCD was in case the cranks varied in any way.

Bit of trouble to find a proper crank but not bad for $31 and I plan on taking off the 52t to move the 42t up front and use my Surley 38t in the middle which my chain is used to using by now.
