    Trek 1420 Bottom Bracket Question

    I have a Trek 1420 frame that needs a complete bottom bracket assy. I have a NOS Sugino Super Mighty crank set (double) I want to use. What size Bottom Bracket do I need ? I know it is English threads and 68mm. But what length would I need ?

    '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
