Here's the alignment fixture all set up and ready for action. Before welding, a protractor is used to set the pinion-snubber support at 0 degrees horizontal to the floor. Then each outer axle-bearing carrier end is also zeroed with the protractor before welding as shown. This move ensures that the brake backing plates and shoe assemblies will be level after reassembly. The Suttons can narrow any type of axlehousing. The empty cases in the foreground are used for aligning the tube ends of (left to right) Hotchkis-type Olds/Pontiac, '55-'64 Chevy, 9-inch Ford, and 8-inch Ford axlehousings.
