ALL AMERICAN-- I hear your pain.  You will always spend more restoring a quad than what you will ever get out of it if you sell it.  From a dollar stand point you will almost always come out ahead to take your time and watch the internet for what you want built like you want...I have seen some sick zillas with full rebuilds and the best parts go for 2700 to 3600.  Im sure they had 2 to 3 times that much in them.... however...

Part of the fun is building what you want how you want and the pride that comes from knowing "you did that.  You built that.......Even though OBAMA will tell you  "YOU DIDNT BUILD THAT"     ---and budget usually requires it to be in stages.

Fact is you have an old quad and everything wears out and new better parts come along.  If you dont have the money to build it what you would like.....than ride the hell out of what you have and enjoy it.  my .02
