I have to give a tremedous shout out to one vendor for parts.

My rear differential housing rusted all the way through. It was like an egg shell from all the salt they put on the roads up here in NY. Everywhere I looked I was finding a replacment for $700-$1200. Just the housing, not the parts that go inside (axels, differential gears, etc.) I shot them a email asking if by any chance do you have this part. They say they have tons of parts so I figured 'What the hell'? These guys emailed me back within two hours. Not only did they have two that would fit, the price was SO good I couldn't believe it. So talking back and forth and I'm figuring there has to be a communication problem cause the price they are asking is incredibly low. Well, I just put it on my truck today. Used differential/Axel housing with no rust for $150. Yes. $150. $100 more to ship it. Wow! I am very happy. If you guys need parts, drop them a line. They'er out of Denver, CO.
