Well when i did my clutch job i used the hayness repair manule as a refrence i would also try the chilton too. The haynes was OK it could have been better. I also used this site as a refrence too.

I really didnt have to use these that much do to fact that it was pretty much straight foward. As long as you a familure with the parts of a car how things go together then i would say your all set.
GOOD LUCK
CORY
