Anybody heard Ten Factory Axles? I want to build a new rear end and ordered ford racing diff. new gears and bunch of other stuff but when it comes to the axle shafts we don't have too many options so I ordered Ten factory axle shafts from summit racing for $220 it says it is a direct replacement and has 10 year warranty. My local mustang shop says they are garbage. What do you guys think should I send them back and order Moser's which is $400 or give it a try?
