I have a 65 bug I'm installing avis adjusters in. The problem I'm having is removing the original center support for the torsion leaves. My beam has 2 gooves stamped for holding the center section.

Is there an easy way to remove the center section? I already did one of the beams but it wasn't easy. I only cut out one of the grooves and beat the center section out with a pipe. Are you supposed to cut out both grooves and weld a plate over the other groove that doesn't take the adjuster?

I've done the search and it seems there are different factory ways of retaining the center support. Does the "other" groove have to be removed to get the new center support in? It seems that by cutting out both grooves the beam strength would loose some of it's integrity.

Any body have any tricks or tips?

Those grooves you're referring to are the dimples that lock the center bearing in place. An easier method to remove them might be if you drill both ends of the football dimple out with a 1/2-inch drill bit. Then use a die grinder to remove the remaining center section.
You do NOT need to remove the center bearing. You only need to break it loose so that it will move freely up & down. That's how the Berg instructions describe the process. Hope that helps.

Are you supposed to leave the original center support in and not use the one that comes with the new adjusters? :?

by the new center support do you mean the curved tooth plate?

Are you sure you have Avis adjusters and not Select-A-Drop adjusters?

The kit comes with a new center support that goes inside the tube, 2 "toothed" pieces (one to weld on and one to adjust), a bolt, and 2 nuts. The dimples in my beam are about 1" long on both sides of the beam. The new center support is a round collar that fits inside the tube and accepts the torsion leaves like the original collar. The original center support is the same except it has grooves machined in the outside edge of it on both sides where the dimples hold it in place.

I think you have to remove both dimples (1" long on both sides of the beam) to get the center support to move.

my berg avis adjusters did not come with new center support to put inside the tube.

I agree, never seen or heard that before

This is a schematic of the center bushing inside a beam.

You're trying to tell Bill & I that your Avis adjuster kit came with a replacement piece for it? Here what an Avis adjuster looks like when installed.

The center bushing remains intact. No need to remove or replace it. it just has to move freely up & down.

The easiest way to do it, may be to cut a section out of each tube, like you would with a select-a-drop adjuster, and weld in a new piece with a slot in it. Then weld the avis adjuster on to that.
The only drawback that these adjusters have is that you can't adjust the ride hieght with the weight of the car on the ground. There's a bit more trial and error. In the case of off road cars, you can't "preload" the springs easily either.

Yes the kit comes with a new center support. In order to make the old center support work the dimples/creases in the beam must be removed

I agree, the Avis adjusters I purchased (Moore Racing?) came with a new center section. I ended up drilling and grinding those dimples out, and then after I welded the adjuster in, I added a piece of flat stock around the tube. This may be hard to explain...I took a 1 inch wide piece of flat stock (1/8" thick?) and tacked it onto the upper edge of the part of the adjuster I had welded onto the beam. Then I was able (by keeping the flat stock peice extra long) to bend the stock around the beam, tacking as I went along. When I was at the bottom part of the adjusted, I used my angle grinder to cut it off, and used a large c clamp to pull the end down tight to the tube. I then finished welding both sides.

Thank you! I knew I wasn't the only one having trouble.
