Rear end advice for racing with a 4 speed

My guess is that you will need an abrasive blade chop saw to cut em down, cause they have to be hard. A hacksaw or band saw ain't gonna get it done.

That goes without saying, yet when abrasive blades are used to cut they create heat annealing the surface area within the heat affected zone.

Next time I narrow an 8 3/4 I'd prefer to order custom axles from Mosier.
