RS Motorsport :: Classic Speed Restored

I'm making up my own tramp kit for my later suspension Mk1
It's going to be ajustable to set pinion angle, and using solid bushings on the axle end.

I want to use standard body brackets, so If wanted I can later use standard links.

I was hoping someone has the dimensions, I have several good photo's

The most Important measurements are shown on this pic
Also please, the diameter of the bolt M12?

worked out from the other thread that I can figure out the height, "B" from the chassis rail depth

But still need the other two dimensions,
I can go out and buy a stock bush and then will know the width "W"
But I guess W=Bx2?

Can some one PLEASE measure it for me?


on another note, I'm surprised with five or six companies producing them, the dimensions aren't listed online anywhere....That I can find.

I'm thinking of making the axle brackets bolt onto the sway bar mountings.

Can't help with dimensions for you sorry, but will try and find them.

But a couple of thoughts popped into my head, which may or may not cause problems.

What springs are you going to use? if you use a fixed leaf e.g bushed at the front eye, and swinging shackle on the rear you could have issues.

How is the adjustment going to change pinion angle if you are using fixed leafs? The diff housing will need to rotate, so that means the spring saddles/seats will also have to rotate, surely this will cause the springs they are attached to to twist in an "S" and be preloaded.

Secondly, if the bushes are fixed, and the springs have a bushed front eye, then the suspension will bind as it compresses,
this happens to an extent with the original radius arm setup from Ford (as is discussed here often) but is reduced to a degree by the bushes allowing some deflection which effectively allows the distance between the mounting points of the radius arm to change, which in turn allows the curved spring to flatten out etc as it compresses.
When the bushes are solid, or rose joints are used both ends the arm fights against the spring.

This is why 4 linked cars run either Slipper type leafs, to remove the fixed point at the front of the leaf.
Alternatively using coilover springs eliminates the issue, so if you are doing this then it may work
