Mirror extenders adapters risers

1981 KZ650-CSR w Emgo Euro bars from Z1Enterprises.

Looking for some mirror extenders or risers --- probably something to add 2-3" in height.
The stock mirrors on my bike are too short for the Euro bars I installed. My mirrors are in very good condition, so I'd rather get extenders than replace them. I haven't had any luck finding a nice set of oem long stem mirrors, and I've already got a spare NOS set anyway, so I'd rather not buy more mirrors.

The risers below are only 20mm, so they probably won't be long enough.
There are offset mirror extenders, but I'd prefer straight. Thanks.

My brother used to have a GS550 suzuki (very early one) that came stock with these extenders that had rubber inserts in them to help with the vibration.
Chrome, just about 2" long as I remember.
If you can find some watch out, suzukis had a right hand and left thread on their mirrors.
You will need two from the left side.
Maybe from a recycler ?

Thanks. I didn't have any luck w that, though.

I have a lathe and can make ya a couple if you want.
Just tell me threads you want on them (both external size and internal size) and the preferred length and I'll make a set this week for you.

Also, email your ship to address to me; EaracheMS @ Gmail. com
I'm in Indianapolis - you can pick them up if you happen to be close by.

Thanks. PM sent.
