Hi all, I have a '71 Javelin SST with bad axle / hub (Amc 20). I want to replace the two piece setup with a single piece design. There are two companies who claim they can supply these. One is called Moser Engineering and the other is called Superior Axle & Gear. Does anyone have any experience with either of these companies and has anyone done the swap themselves? If so, I'd be very interested in your comments. I don't want to go down the path of finding used AMC 20 axles for numerous reasons. thanks!
