A Hurst Competition has horiz bolts to hold the shifter lever.
But.... You may have a David Kee modified Hurst shifter that takes the OEM shift lever.

See this thread
Shift lever w/ reverse lockout?
If so I'd give them a call.
This site sells the rubber grommets and well as the needed shoulder bolts.
