driveline geometry suspension for OME install ?

After reading this well written article on driveline geometry and the section that is cut & pasted below:

Question

2005+ Tacoma DCLB 4x4 with OME spring leaf pack and Shocks installed, does this rotate the axel pinion up or down (Don't have my OME installed yet or would have my answer as it has not arrived)? Have not taken the driveline dim. check yet of pinion too carrier drive top and bottom. As I understand the article for spring over axel (SOA) if the pinion is rotated down then the shim would be fat end forward to correct the geometry and of course opposite if pinion is up.

Bmoose build thread for regular cab installed his shim fat end forward.

Others have reported shim installed thin end forward for geometry correction.

Do I have this wrong? All answers welcome for my conundrum.

Apologies for the charts and verbiage not setup as shown in article.

If you have a leaf-spring suspension, then there are more options available. Among the options are shims, rotated spring perches, longer or shorter spring shackles, or driveline changes. Below is a table of common lifts and driveline affects:

Block None None None Tilt UP Tilt UP Tilt UP
Shackle Tilt DOWN Tilt DOWN Tilt UP None(3) None(3) Tilt UP
Lift Affects on Driveline; Direction to tilt the pinion to correct angles
Notes:

Front axle with shackles forward
Front axle with shackles reversed
Affect varies with length of spring, shackle and driveshaft length
Installing a shim between the axle and spring is the easiest way to correct the driveshaft angle (here's a convenient on-line source for custom-built axle shims). But which way does the shim go in to fix the problem? It depends on the spring and axle configuration, namely Spring-Over-Axle (SOA) or Spring-Under-Axle (SUA). The following table summarizes the direction of pinion tilt vs. axle configuration. and which way the "fat end" of the shim faces:

Tilt/Config Front/SUA Front/SOA Rear/SUA Rear/SOA
UP Backward Forward Forward Backward
DOWN Forward Backward Backward Forward
Pinion Tilt vs. Spring Configuration
Its best to visualize the spring as fixed flat surface under the vehicle. Then the shim will sit between the spring (top or bottom) and the axle, which then must rotate up or down to align the spring perch of the axle with the angle of the shim.

 

It tilts up , the shim tilts it back down .

Thin edge forward

 

Alas, the table you attempted to include didn't survive the formatter.

Try using a mono spaced font such as Courier, and the #code BBS tags.

 

Thank you OZT.

bjmoose thank you, I got the link to the article from your build thread. Also your build has given me the confidence to complete my own build. Again much thanks.

On the format of the chart , your suggestion is fascinating but mysterious.
How would I do that?
