I decided to go 24 spline on my EV project since I had to regear and was doing bearing as well.
Before making this decision I had gotten the rear end caps (flat style) blasted and powder coated. Also NO CVs, but just the front shafts thrown in as well since I no longer have a need for anything 10 spline. How does $100 sound?
Also, have 10 spline diff carriers, 3.54 ring and pinions, and some older dome style 10 spline rear shafts if anyone is interested. These might need discussion with Jeff and Ed in pricing since they are theirs and will be passing on the proceeds to them.
