Lots of 8 3/4 rear questions, brakes, bearings, etc...

I am building an 8 3/4 rear and need to know a few things.

I have a 9 1/4 rear that has the heavy duty drum brakes. I was wondering if the backing plates and all the brake parts will work on the 8 3/4?

Also wondering if Green bearings are the way to go? I was looking at this kit and thinking it may be the way to go.

And if so, do I need these special nuts for them?

Also, I need to find U bolts and the shock brackets for the 8 3/4. Anyone know where to get them?

Thanks, Jeremy
