Even if you pic one up to have it narrowed, talk with the shop that will narrow it for you first. They need the housing/axles to be at a certain length range in order to do the job correctly.
Next, the center section and axles. You need to consider what gear ratio you'll want, posi or not and so on. If you plan on running more than 300 hp, you will want to stay away from 28 spline axles. Finding the exact combo that you need can be tough.
Finally axle mounts. Fabricating the mounts yourself to fit you car can be a time consuming challange. I'm not sure but someone may sell an after market mounting bracket set for a 9".
All that being said, there is a huge advantage in ordering the complete set up from a supplier once you determine what your needs are. With the 9" being as popular as it is, there are quite a few suppliers that can set you up. The one I ordered for my Skylark will hopefully be here tomorrow!! 
Good luck. |
Thanks for the run down! Sounds like it will be pretty much the same price then? I'm a 19 year old college student so I'm trying to get the best bang for my buck because $ is tight! Good luck with your build! Thanks
