69 Jeepster Commando Suspension Lift And Pinion Angle

[Tom Bryant]

I have been wrenching since I was a kid and have had lots of 4x4 truck, but I am new to Jeeps, I have a 69 stock Jeepster and am planning on changing the axles from "over spring mount" to "under spring mount to lift it approximately 4". I will relocate the spring perches on the axles to accommodate this but, am looking for information about correcting front and rear pinion angle once the lift is complete.
Can anyone point me in the right direction???

Which axles will you use?

Pinion angle is the least of your worries.
People think a spring over swap is a quick cheap way to get a bunch of lift but it's a mess to do it properly.
Very difficult to get the steering hooked up with decent geometry. If you still have the stock steering for the 69, plan on replacing everything.
