I do't have a pic but I would recomend installing the front bushings with the hole off set to the inside/away from the ball joint and the rear bushing with the hole offset to the out side/closet to the ball joint on each arm. This will give you the most possible caster and that is what's lacking from the factory set up's.

Also. be aware that even IF you find the instruction sheet, it might NOT show the installation for maximum increase in caster. Instead, it might show how to install to get the most increase in camber. The two methods differ in how the rear bushing is installed. Both methods would have the front bushing installed so that the control arm is shifted OUT.
To increase camber, the rear gets installed the same way (shifting the arm OUT). To increase caster (which is what you want), the rear gets installed shifting the arm IN, as is shown by the diagram in the post previous to mine.
Good info! Thanks...
EDIT - My bad...

Also, can any one explain simply, what a positive caster does for handling?
Thanks.
The more positive caster a front end has, the more it "wants" to point straight ahead. What this also means is that it takes more effort to turn it away from straight ahead. When vintage Mopars were originally built, one of the perceived benefits of engineering cars and creating alignment specs with little (or negative) caster was reduced steering effort. Concern with better stability and handling trumps that in today's world.
Another analogy for positive caster stability would be riding a bicycle. Bikes generally have positive caster. If you extend an imaginary line through the steering pivot (the front frame tube holding the fork/handlebars), that line intersects the ground forward of a vertical line through the axle shaft. Because of this, the wheel "wants" to stay straight and track "behind" the imaginary pivot line. This is why, at speed, one can ride a bike without even holding the handlebars.

Do you guys recommend buying the OFFSET bushings all the time?
Stock '70 valiant in desperate need of Uppers. Just trying to get a handle on it. NAPA sells 'Stock' and Additional Caster Adjustment ones... The car is stock, If I go with additional caster bushings, will it be a problem? How tough are these pressed in? Can I get them in with heavey hammer and Big socket to straddle the rubber?
'75 CJ5 with all glass body and a 350 Chevy SB '85 Chevy Stepside (the wife's) '89 Volvo All 100% maintained by me. '70 valiant DD for my son '74 Dart Swinger..Latest endeavor http://home.lyse.net/brox/TonyPage4.html
