A while back I put a a520 in my 85 omni since my a525 blew up. Currently I am running unequal length axles, and am getting tired of torque steer. After using the search feature I've come to the conclusion that the 87-90 a520 or a555 intermediate shaft will work. I'm not worried about axles. There is lots of information on axles, so I know what I need to go with. I have not found a good enough answer about the intermediate shaft though, so I've decided to come out and ask. Thanks
