I recently was gifted a very minimally ridden Guerciotti track bike that I've started to build up, but I ran into a real snag today with the bottom bracket. I had ordered a new Record Pista crankset/bottom bracket, but when I put the crank arms on, the spindle was nowhere near long enough, and the non-driveside crank was actually hitting the chainstay. The spindle length is 111mm, but it looks like it'd need to be at least 117 to get the crank arms spinning freely.

I think the problem is that the chainstays are huge. Way bigger than I've ever seen on an old track frame like this. Have any of you run into this problem before?
