where to order axles

I thought Cass was about 300+ shipping with greens and long studs.

New high-strength 30 spline 8 3/4 axle package. Most lengths. Includes green wheel bearings and standard length lug studs installed. $300 pair. Choice of standard length, or 3" lug studs.

That's from his ad on moparts... The axles have plenty of spline to shorten 1" from stock A body.
