Clutch Replacement
What is involved in replacing a clutch. I have a 68 F100 strught 6, 3 speed. If someone could give me a step by step list I would appreciate it. By the way are there any shop manuals available for my truck.

You can drop the $50 bucks on a '68 manual on CD from the site's store to get you by in the short term, but sooner or later you'll probably want to upgrade it to a real set of manuals. At least I did.
Like many scanned documents there is a focus issue with the '68 Detroit Iron book on CD, it really hurts my eyes to read many of the pages. Plus, you have to print out whatever section applies to your project-at-hand in order to be able to read it out in the yard. (That CD and the laptop it's in will slide right out of your hands if they have a respectable amount of grease on them.) So, eventually you will wind up with everything you're interested in being printed on paper, and that is called what?? Yep, a book.
Check on e-Bay in the auto parts and accessories area. If you can't get a set of books there for your '68, a set for most any truck in our series will prove satisfactory.
Regarding your clutch question, I replaced my clutch three times and couldn't get any of the new ones not to chatter. They were new, too, not reman. The flywheel was resurfaced for the first replacement and rechecked when I did the second one. When the third clutch wouldn't work, I put in a c-6.

Use a diaphram type clutch. They take less effort to push in and don't chatter. I would not use the three lever type if they were free.
If you can beg, borrow, or build a transmission jack, it makes it much easier to do. Remove the driveshaft, clutch linkage, etc. Slid the transmission back enough to have room to work.
Get the flywheel resurfaced. If the ring gear teeth looked chewed up, replace it. Most clutch sets come with a plastic alignment tool to center the disc while you tighten the pressure plate. Torque the flywheel and pressure plate to specs. You can do it!

Never done it on a straight six but put a jack under the rear of the engine to support it. When the tranny slides off I think the motor will tilt back and stress the mounts.
