Re: Roaring Forties #36 - Mark Worthington\'s GT40

Here's the rear suspension setup on my RF. The upper and lower drag link front ends attach to chassis mounts near the firewall with AN8 pivot bolts, and the drag link rears attach to rod ends which attach to brackets, that have a high-tensile 3/8" bolt welded to them. The lower bracket goes through the lower upright, through the lower arm, and through a bracket which makes this a double shear attachment and the bracket also serves to locate the lower damper mount. The rear end of the lower arm mounts to the upright in single shear. The rear of the upper drag link mounts to a bracket which has a high-tensile bolt which runs through the rod end on the outboard end of the upper link, which then mounts to the upper upright. All the 3/8" fasteners use high-carbon-steel ferrules (sp?) where they attach to the rod ends...the ferrules effectively increase the diameter of the bolt and distribute the load.

I posted another thread on this forum about the pros and cons of chrome-plated suspension bits, but have researched the matter and concluded that, for a car that will only occasionally see track duty and that will be frequently inspected, I am not concerned about the chrome plating.
