Crazy AL u r amazing and very insightful........you must be a master mechanic or race car builder and wise beyond your years I am sure. Thanks for the input and I will be getting all this done in the spring and that way I have the tools and know how to be sure all is correct when the install of theparts is done (not by myself though).

Thanks for the kind words,

I am not a professional auto mechanic, but I been wrenching on cars since I was very young. I enjoy vehicles of all kinds so I also wrench on motorcycles, four-wheelers, and so on. I worked as a mechanic at a speed shop when I was in college. And, my previous (pre-mustang)bighobby was 4x4s. At the moment I'm selling the remainder of my 4x4 parts, and I'll probably turn that into a new motor for the stang.

My background is mechanical engineering. Professionaly I design and manufacture labratory test equipment and I consult for a few different companies. I mentioned in an earlier thread that back in grad school I helped design and build a brake dyno. Well, at the moment I am working on machinery that the auto industry uses to evaluate the durability of plastics and paints for auto bodies, dashboards, and so on. It is unbeliveable how much engineering goes into a car these days.

i want to be like crazyal when i grow up, LOL!


thanks a bunch

just a tip when measuring your pinion angle. Don't leave the angle finder on the pinion flange or drive shaft. You'll know right away if you do, but it won't fall off until your doing over 10mph.

Seriously, I have left mine on twice and the second time i had to knock it off with a broom handle because there's no way I can fit under my car far enough to reach the drive shaft.

I know this is an old thread, but I disagree with the pinion angle setting of a 1 pc. driveshaft. Settingthe pinion angle and the method of doing so is correct. The parallel pinion angle however is incorrect....especially for taking it down the track. If both the pinion and trans are parallel at rest, you are at optimum driveline power. If you launch a car at 3K rpm for example, the pinion will rotate. If the pinion is set at zero at rest, the pinion will rotate 2-3 degrees at launch....thus not giving optimum driveline power. You still need -2 to -3 degrees with a single pc. driveshaft. That's roughly the rotation of the pinion on a S197. It will vary some based on suspension components, weight, hooking up etc. This is why a ladder bar car has a totally different pinion angle than a leaf spring car. The pinion angle on the ladder bar car will be smaller (less travel) than the leaf spring car (more pinion travel due to spring wrap). To find the OPTIMUM pinion angle for YOUR car is trial and error. start at one point and work you way up or down.
