What BB size for Trek 1500?woofers

I got myself a Trek 1500 frameset, and want to build it up. I'm going to use either a 105 or Ultegra crankset (new) and my old 8-speed parts. What BB size should I use for this frameset?

Thanks!

English thread, 68mm shell width. 9 speed 105 or ultegra doubles use the 109.5mm spindle length,and triples use 118.5
thanks Rusty! (nm)woofers
