Outer Limits 4x4 Board

As the subject says, I am going to convert my NT to WT diffs but staying SPUA.

How do I go about keeping stock castor angle? and should I point the rear pinion up a little to help with shaft angle? Pictures would be great if anybody has got some.

Thanks Andy

If staying SPUA, your caster would still be pretty much factory. Unless you are planning stupid amounts of spring lift, you shouldn't have much issue with your shaft uni angle unless you are getting massive flex.

I have done a few diff conversions on Toyota's , Holdens and Fords. The Suzuki WT with NT spring spacing is my next one.
To keep stock caster angle I turn the diff upside down and place a spirit level on the spring plate.(in the same direction as spring would sit)
When diff is level,remove spring plate with an angle grinder and reweld one bracket at a time making sure its still level. The hardest part is getting the measurements right.

That's the way I have done it. Remember, measure 20 times, tack, measure another 20 times, weld.

I have pulled some SPOA cars apart and seen some "interesting" variations in caster and pad spacing from one side to the other.
