Default Re: Alf Wiebe A body rear control arms

If I'm looking at the pictures of Alf's stuff correctly, the ends of the lower bars do not have spherical rod ends, nor are they adjustable. Now, there are other brackets on those arms that have solid rod ends that are adjustable, but the ends of the lower arms where they attach to the frame bracket and where they attach to the rear end housing have bushings and are not adjustable. The attachment point at the front of the lowers is possibly a gray area.

The front attachment point is kinda sneaky. The original bolt hole in the frame is not the front pivot point. There is a bolt there, but the control arm has a larger diameter "hoop" which at best is a safety loop. The actual attachment point is a heim end that hangs below the frame. Any heim is considered adjustable in my mind.

Cool Re: 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.

Greg, Do you mean that the front pivot point is now located back at the original frame bracket and hole?

Mark-- Yes,the one shown me at the Fontucky Sports Nationals was just like that.It had no lower bracket or lower heim joint. Oh,yes.No offense intended to the inhabitants of the beautiful green state of Kentucky. If you want a real cultural awakening of shocking proportions,drive just north of the track through the residential area .

Near as I can figure, Alf musta seen the handwriting on the wall. I'm surprised the original design has been okay as long as it has.
You know ,when those things first came out, there was an article in SS &DI on Alf's Buick, by Wayne Scraba , who was the ND tech writer too. That's probably why nobody from NHRA looked at them closely.
After seeing the article, I couldn't figure out how the things could work .
Later I found out there was a certain little part omitted that couldn't be seen in the pictures.
