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 ?

Interesting reference. I noted that these cranks take an ISO taper spindle, not the more common JIS, so that will limit the choice fo bottom brackets too.
