moser axles
Do what Jim Lusk and the guys said.
I ordered the M30cst-AB45 for my 1970 Duster. The OEM is plenty strong, in fact Moser will tell you they are 90% as strong as their racing axles. They are A-Body OEM with the B body drum brakes which has the Big Bolt Pattern.
I order the Moser axles, green bearings, and 1/2" studs from Moser through summit. At no charge, Moser installed the bearings and studs.
Then shipped them w/ gaskets to my house. Shipping was through Summit-$12.95. plus tax, since I lived in Ohio.
Go through Moser and you'll pay higher shipping for sure.
