I hope I can help you understand your options.
The stock Mopar linkage is a fairly long throw, but the main problem with it is the rubbery feel. To me it feels as if the shift handle is not solidly connected to the linkage. For example, when shifting from 5th to 6th, if you are not bearing right enough, the centering spring will pop you back to 4th without much feel to tell you what happened until you let out the clutch.
The stock Mopar linkage requires a shifter handle with a square post. Two through-bolts hold the handle in a socket that is about about a 3/8" square inside.
The after-market Hurst linkage (also sold by Mopar) is about $350 or so and consists of entirely new shift linkage that you install under the console. The advantage of this linkage is that it shortens the throw and entirely eliminates the rubbery feel. The shifter feel with the Hurst is the best I have had on any car.
The Hurst shift linkage will accept the 3/8" square post on the stock shifter handle and there is also a corrugated flat area that will accept any of the traditional Hurst handles you find on their website.
Gunslinger makes the shift handles with the 3/8 square post. Hurst makes the shift handles with a flat, corrugated face about 1" by 3/8". There is a picture of a traditional Hurst handle here:
M6 Pistol Grip Shifter Prep you can see the flat area with the corrugations that fits on the Hurst linkage.
The Hurst handle with the carbon fiber grips is about $150 from Year One. The (plastic) wood grips are standard on the Hurst handle, the carbon fiber grips are an extra-cost option.
If you go with the Hurst linkage, follow the noise control procedures in threads on this site. Or PM juve996 for his advice. Otherwise you hear transmission noise under some conditions, also buzzing at certain rpms.
