Shift **** adjusment
I just added a B&M SHort shifter. I also have a ball shift **** with C% logo. The **** uses a special nut (odd shaped nut) so that you can make sure the logo is centered and thenyou tighten the nut.
The new shifter is lower and if I take the nut oout the ball sits nice and low, just the C5 logo is upside down. If I use the nut it raises the ball back to stock height.
How did you guys do it? I hope this made sense.

Easy, eliminate the jamb nut and use shims beneath the **** to adjust the C5 logo where you want it.
The shim(s) can be anything of thickness that gives you the desired results...washers, button head allen screw set into the "Demon key" milled slot (if present in the B&M), small OD nylon ball, etc.
The other option is to cut off some of the top threaded portion of the shift lever to compensate for the **** locked in place with the jamb nut.

If you want to adjust the **** by shimming, it would depend on what is bottoming out on the **** first, the shaft inside the **** or the bottom of the threads on the shifter. If you put something inside the **** to adjust it, be careful not to tighten the **** too tight or you might crack it. I would just try to modify the nut.

Jamb nuts are by nature, thinner than a regular SAE/metric nut. Holding on to a jamb nut to cut or grind will not be an easy task with typical hard tools. A machinist could easily accomplish this process though.
I don't see how a 2"-2.25" typical **** would crack if hand tightened to much. I doubt that one could torque it that much. My HURST **** has internal brass threads.
I hadn't considered what might be bottoming out on the **** that shimming may or may not remedy.

Some Hurst ***** do not have the hole threaded the full depth of the **** so they will not accept the full thread depth of the Hurst (and stock) shifter. I ordered a **** from an eBay supplier, and he makes sure the ***** are drilled and tapped past the brass threads. I was cautioned not to tighten the **** too tight, so evidently, it has happened.
My Hurst **** will thread all the way down,where no threads are showing on the Hurst shifter.
