Installing rear shocks on the Z28 and noticed that my KYB shocks have a step on the bolt to keep the shock away from the axle and the Koni just gives a bolt with no step. I cannot use the old bolt because there is a diameter difference. What do you guys do?
I guess I'll just stick a 1/2" worth of washers in there to take up the space. It's a shame these big name companies can't get it right. I had similar issues with Bilstein shocks on my Vette.
Uh. What exactly is the issue with the Koni bolt? It works fine. There is no issue with the hex on the inside touching the axle.

If you look at the picture I've attached you see where there is a spacer about 1/2" that keeps the shock off of the frame on the axle. Every other shock manufacturer I've seen has this. Not having a spacer there changes the angle of the shock. When I looked at the shock I installed last night the bolt itself was wanting to angle downward. This does not look right and if I break the shock because of this I will not be happy.
You are over-reacting. First off all, not everyone does this the same way. The shock won't hit anything, the stock shocks use a setup that is the same as Koni, except they have two wrench flats instead of a full hex in that location. The KYB is a cheap setup that uses a generic bolt that can be used on other vehicles to save money.
Further. When the suspension moves, that bushing flexes, and when it's in full droop like on a jack, it's the most angled it will ever be.
Put the shocks on, they are fine.

I've been using the bolt and nut setup that came with my Koni Str.ts and they are still running fine.
So I checked a couple of local cars that still have the OEM shock on them and they have a spacer from the factory built onto the shock. I added a home made spacer to mine. Just in case anyone is interested.
Well okay... but the hex acts as a spacer and works just fine.

It was asked of me to show some pictures of how my car looks after the suspension rebuild. Koni Str.t on stock springs.
almost forgot from the ground to the center upper most of the fender well
Front -- 27 1/2"
Rear ---27 3/4"
Uh. What exactly is the issue with the Koni bolt? It works fine. There is no issue with the hex on the inside touching the axle.
When installing these should we be using the Koni supplied hex nut as shown so that it acts as a spacer and then adding another nut to secure the assembly to the shock mount?
If so do you know what the thread of the additional nut is?
