Thanks guys, it seems so far, the best idea is to go with the M/C with the 1 3/8" bore.
I have already adjusted my brakes. I put the whole truck up on jack stands, and spun the tires until they would just barely grab and then backed of 1/4 turn.
Dang, I wish that was the problem. Also, before I 'buy' a new M/C, I will try to adjust the pedal booster rod length.
Boy, that would be an inexpensive fix.
It will be the weekend before I get to try these out, but will give an update as to what the final fix was.
