I just got a Centurion Super Le Mans frame, and I was wondering what size bottom bracket i need. I measured the width and its a 68mm, and it is threaded, however the inside dimension only measured 35mm. Is this standard? most bottom brackets I see only say which width and the overall length of the bracket. Any help would be great!

it just looked small to me, but I found out 68mm is the only number that matters
Are you installing an entire bottom bracket assembly? In addion to the 68mm shell width, you'll have to match the spindle length and shell threads
