Alf Wiebe A body rear control arms

A local Chevelle racer showed me an updated version of the Alf Wiebe lower control arm which had the lower attachment point relocated to the original location through a bushed hole,no heim joint.That revision should fly because the arm is no longer adjustable,and the heim jount is at the upper rear attachment point like the others.This facilitates pinion angle adjustments. It would be fairly easy to update the earlier bar assembly to this configuration. Seems to me that the bushing centers were 22 inches apart on the stock lower control arm. All the upper wishbone does is locate the centerline of the rear end from side to side. It does use the stock upper frame brackets and bushing locations on both the car's frame and the axle housing.Hopefully, an official word will be forthcoming soon. Neither car that we are planning to run at Winternationals has the Alf Wiebe arms installed yet, so we'll see what happens then.Hopefully,we can continue to use them after a small modification.
