You don't need to mount the triple on your GF's bike to measure the chainline. When you get a 111, mount it on your bike and check.
if i am reading their sight correct the old(er) cranks are as follows:
double = 111
triple = 115.5
What does "older" mean? 9-speed (1997) may use those lengths. 1997 certainly qualifies as "older".
I'm convinced that the Racing-Triple takes 111mm symmetrical. '93 and '94 "Record O.R." triples take 111mm symmetrical (same as Record). "Racing-T" in '95 replaces Record O.R. and is a flavor of Athena. All Athena 8-speed take 111m symmetrical. '95 Parts catalog does not list any spindle length options for Athena, or any other BB (except Veloce - also 111mm).
While the chain line for R-T may be greater, one does not necessarily need a longer spindle to make it so. The design of the arms is quite enough, and R-T has unique part numbers for the arms.
