Thanks for the response OldSub.
My project is a 54 1-ton dually with dump bed. Currently it has the original single master cylinder. I am wanting to put a dual master in with boost but wasn't sure what to expect. I'm going to have drums all the way around (original front, 14 bolt rear on back) for the time being though. I just thought that a brand new modern dual master with boost would be far better than the antiquated single master. I better do more research in the case you are describing.
Thanks
