[Mgs] Gear shift knob

[Barrie Robinson]

I got a beautiful gear shift knob from Larry Heaps who can be found 
on www.britcot.com - it was for my under restoration Aston.   But, as 
usual, Brit threads are different and it will not fit.     The gear 
shift thread is 5/16 with 22 pitch, the knob is slightly larger than 
5/16 with bigger thread.  There are some inserts one can get but I am 
damned if I can remember the name and what they do.  Can someone help 
here please? - Thanks in advance for responses.

I tried plumbers tape and that was hopeless.

Regards
