Hello everyone so I have had 2 other post regarding this conversion
My new question is has anyone used or have info on using a 1962 cadillac dual bendix master cylinder with the 4 bolt to vacuum booster
For this conversion

 

I have often wondered about that, too. I wonder if the single master cylinder for a '61 Cadillac is the same part number as for a '61 Olds. That would be a pretty good indicator that you could swap the '62 cylinders.

 

Rund to Rund suggested this from your other thread.
If two of the bolts/studs are in the right positions, just use them. Also make sure the pushrod length is correct for the new plunger and the distance it must travel. You can use a longer pushrod with a bolt pattern adapter (make it yourself) if needed.

Maybe this from the Cadi site will help:
