it's a buggy that got discontinued 4 years ago and manuf. only have to make parts available for 5 years after something is gone. I bet suppliers stopped bying parts because everyone stopped bying MBX4 stuff awhile back. So you may happen to get lucky and find a shop with the parts you need but most likely they are sitting (dusty) in a warehouse somewhere.

I think your best bet at this point Rob is to buy complete rollers whenever you can. People are practically giving them away. My buddy picked one up at the end of '05 for $40 for a complete roller. Not saying those deals are everyday but $75-$100 for rollers is not out of the question. Then you have spare CVDs, diffs, etc...
