Shimano Sante BB Spindle Length
i've been wanting to install Shimano Sante double cranks i got off the 'Bay, but after discovering that my bottom bracket was shot, i decided i should look into a new one...but i'm not sure what spindle length to use. Sheldon Brown didn't have anything to say about Sante in his table, and interpolating from components of a similar era, i got a range of anywhere from 109mm to maybe 113mm.
so does anyone have any insight? or...will it really matter in the end?

Yes.......If it's on the short side you risk not having enough clearance for the crankarms or rings to clear the chainstays. I'd try for 110 and then shim with a Sturmey AW cog spacer if necessary. BB's like Phils will allow up to 2mm of adjustment I believe. So a 110 would have you covered.

I have a Shimano small parts catalog from 1994 or so that goes back a way and the listing for Sante shows it uses a 108mm spindle for both 68 and 70mm BB shells. That's odd because every other crank takes a 2mm longer spindle for an Italian threaded BB. Maybe the catalog is wrong but it says 108mm for either.
It also lists it only available with Biopace rings. I have no idea if that should matter, probably not.

Since individual BB spindles for late 1980s cranksets seem to have now become increasingly rare - and his existing BB is shot to begin with,... does anyone know what sort of right side off-set (or, perhaps none at all) the "D-3K" spindle originally for the Sante double crankset had?
I ask, because perhaps there is a more common, slightly more modern, Shimano "UN"-series cartridge bearing set which would be compatible. These are often still available even at a LBS. But, there were a great many different lengths and even with different off-sets on the drive side. And, I believe the UN53 / UN54 is still in current production. These are available in 107 & 110 lengths... . so might one of these work with the Sante? Seems like this would be a great buy (selling new for only around $20 or $25)... that is, IF one would fit the crank.
