  1. They need to be crack tested, shot peened, and then cryo treated.  Makes no sense to cryo treat parts without inspecting them and doing a proper surface treatment.  Don Potter used to do that to new 280Z stub axles and companion flanges years ago.  For $750 you got those parts plus ARP studs, companion flange nuts, bolts, and washers, 280ZX axle nuts, Japanese bearings and seals, and a tube of Wurth SIG 3000 grease.

  2. NHBB and FAG are about the best spherical bearings you can buy. Tubing wall thickness depends on the load. If you're building a autocross/track car that weighs 2,000 lbs you'll run a thinner wall tube. A 2,800 lb street car that hits potholes will need a thicker wall tube. .095" wall is a good place to start.

  3. Rust ridge on the cylinder walls? Frozen piston rings?Squirt some penetrant in the cylinders through the spark plug holes. Pull the oil pump and check to be sure nothing is I it. Pull the distributor and the drive shaft. Squirt oil on the bronze gear that drives the pump and the distributor. Make sure nothing is in the cam chain. Squirt some oil on the crank gear.

     

    Turn the engine back and forth to see if you can work it loose.
