Dennis- sounds great except that I just rebuilt my 20 with regular internals.
I'll have to start looking for a used overdrive unit. the newones are way too
expensive.
Let's see,  Ill need the over drive unit, a twin 20 and an 18. I think its time
i started my own

    of course, putting in a overdrive 5spd would probably be less work than all
that
searching and rebuilding. Thanks for the info Dennis.
