Fabricating radius arms

[Terrytuned]

Howard the rod is 3/8" I have drilled pre-girling axles and mounted the rear end on top the radius arm (see photo) another way is to mount on top the kingpin.

Howard,
You dont say if your brakes are cable or hydraulic, at least I cant see if you did.
In any case for trials use the standard set up is more than adequate, plenty strong enough and you dont need additional torque reaction rods especially if your on cables.
My second special of many years ago had a dropped axle with repo sports type dropped bronze ends, used in many trials with no issues at all and they were not boxed either. The car was on cable brakes and still stopped very well.

May I suggest you avoid over complicating what you need for the intended use of the car.

Ironically, the time you use your brakes on a trial is when you have to reverse down a section (having failed to 'clean' it). In reverse Austin 7 front brakes work very well, especially if there is some slack in the system.
