I have been looking online for information about which master cylinder to use some web sites say I need one with a 1 1/8 bore and some say 1-inch. which is correct

If in doubt go with the larger bore, hope that helps. | | | | | Joined: Nov 2009 Posts: 33 New Guy | | New Guy Joined: Nov 2009 Posts: 33 | thanks 3b i have single piston gm calipers and a 7 inch double diaphram power booster | | | | | Joined: Feb 2001 Posts: 4,095 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 4,095 |

It's a small world, but I wouldn't want to paint it.
