ack, just to let you know but the FAQ page about the welded samurai diff is a broken link.
Looks like Island 4x4 has, unfortunately, fallen on hard times. I will see if I can find an alternate article on the subject that I can link to.
This one of the problems that an endeavor such as Ack's FAQ faces. Whenever I can, I try to obtain permission to host the article in the FAQ webspace so I don't have to worry about broken links.
The again, the occasional purchase of a bumper sticker or Chilton CD helps keep the wolf away from MY door! I HATE asking for a handout.
Thanks for spotting the broken link!
