rear housing options and opinions

[windsor]

I have a strange S case with a 35 spline detroit locker but that's all I know about it. How do I find which bearing size it has and does that effect axle tube size when buying a housing?

Also, are the fab9 type housings worth the cost for mid/high 9s vs a standard housing? Not looking to spend crazy $ on this rear as long as it will do the job.

Thanks much.

Since you say it has a 35 Detroit Locker it would have 3.250" side bearings. 3" Axle tubes would be fine.
