Source for Koni Rear Shock Absorber Mounting Nuts (4)

[SHELB66]

Does anyone know where I can obtain the Koni rear shock installation nuts?  Standard Mustang ones have different threads as the Koni's are probably metric.  I purchased a set of very low mileage shocks but the nuts were not included.  Any help would be greatly appreciated!

Early Koni shocks use different nuts then later ones which use a metric nuts. You should determine what you have. There are model numbers and date code numbers which will help determine which one it is. I don't remember when the switch over to the metric nuts happened. Probably some time in the 70's .  If you not sure which are which you should post pictures so someone can help identify.

Here are some pictures of one of the shocks.  It appears to be from 1994.  Craig R.

I believe that later made shock uses the large metric size nuts. At least large compared to the smaller nuts used on the originals.They don't have to be anything special since they aren't original anyway so I have gotten ones in the past at a well stocked hardware store. Sorry I don't have a size to give you for a online purchase.

The large size nuts will not fit under the assemblyline type beehive shaped rubber nut covers so there's that too.

Thanks, Bob, for the info.  I did message KONI so maybe I can get the size from them.  I could always buy an inexpensive assortment of metric nuts and hope to get lucky!  I would first go to a hardware store so that I could get a visual of what's available.  I would bring with me a non-metric nut for external size comparison.

Just take the shock with you in the store. I've done that a few times with different parts.

I have a rear in my shop and the thread on the top and bottom is 3/8-24 NF. The bottom stud has a secondary thread for a jamb nut that is 5/16"nc. They are not metric and take standard hex nuts.

They are not metric threads.

Do you need the threads on the front also? As I remember they are sae as well.

Doug the rear Koni shocks which are the ones in question changed thread design over time. They are not all the same. Early made Koni's were SAE thread and later evolved to metric.

I never had a later set.

It would not seem complicated to determine the size and thread of what you have?

I'll know tomorrow as I have a metric thread pitch ID gauge coming.  Thanks!

This is the gauge I have to help me identify nuts and bolts. I found some Koni hardware on a later used shock while digging through some parts today and this is what the gauge identified it as. 

[SHELB66]

That's the same gauge I ordered!  Let's see if we come out with the same "answer".  Thanks for checking, Bob!
