DACCO 762 Torque Converter bolt alignment problem Slant six

I don't know what you're doing measuring that converter. Anyway, that converter matches that flexplate if you can get even one bolt in. Your problem is that you aren't staying organized. Mark the first tab and flexplate hole you try; to make sure you don't try them again if they're wrong. Luck seldom works when the odds are 4 to 1 against you.
