383 '68 barracuda

will be getting shifter rebuilt or replaced - what would be correct for 1968 4spd 383HP Barracuda? What is in there now likely came with 1971 donor car that provided 18 spline hemi 4 spd. but I don't know what model. I have been told that I won't be able to bolt up the Inland /hurst 68 factory 4 spd shifter w/o mods to shifter mount. Anyone know if that is right? There is pretty wornout hurst competition/plus with 2336 on reverse shift lever on there now that seems to do the job. any commnets tips much appreciated.
