Unbelievable, Mine Went Down Too!!!

[Hollywood]

This is just too much after reading what else has happened. I was taking my wife to dinner last night and I started getting some strange noise from the rear end and couldn't quite nail it down so after dinner we were heading home and I also started to smell something burning like gear oil or grease. I pulled over and my wife noticed all the smoke coming from the rear of the car. We got out and there was a lot of smoke coming from the rear end. Luckily my cousin came right over truck and car trailer in tow and back to the house with it.
We took the left rear wheel off and there was spray all over the inside of the brand new wheels I put on Friday. We noticed some nice metal chunks coming out of the wheel/axle bearings which is what I think dissintegrated. I pulled the entire rear drum setup only to realize you have to pull the axle to get to the bearings.
This morning I pulled the other side and also pulled the drive shaft off. I guess now is the time to switch to the rear disc's with an emergency brake.

Does anyone have any ideas where to pick up the rear disc setup reasonably?
I assume having never done this that I need to take apart the rear differential anyway to pull the axle? It has a leak so also a good time to replace all of those seals too!

Any and all help is appreciated.

Thank you, Jim.
