Front Geometry using TE Uprights.

 Counter Stats

Note... TE/TF and TC/TD uprights are different.
The top ball joint is 25mm taller on the TE/TF than the TC/TD.
King Pin Inclination is also set at a different angle.

TE's/TF's are only found in Australia (to my knowledge).
I decided, with a number of others, to make life hard for myself and disregard all the suspension geometry known on the TC, and develop the TE/TF upright instead.  Here is my drawings....

You will have to ensure the chassis is completely clamped down to the build board again.  Just to ensure all is straight prior to using the jig.
Offering up the jig and the brackets to the chassis.  Perfect fit.
Just ensure the front face of the jig is parallel with the front of your building board.  That way the jig is square and the brackets are all square.

Furthermore measure the distance from the front of the jig to the edge of the building board.  Make the other side the same to ensure both sides of your chassis are identical.

A few clamps to keep it in place then a few tack weldes. Before removing the clamps.
To finish weld it all up and you have finished,  lovely. 

Now for the front arm Jigs.

Note this is my build diary. 

I'm not an engineer.  Use this information at your own risk. 

The A arms end up approximately 40mm longer than the standard book suspension.  My jig will be constructed so that the arms can vary in length.  The minimum measurement will be the book length of 340 from center of ball joint to bush pivot points for the lower arm.
