Hey so i want to do something a bit different, ive seen ppl put grenades and other random objects as shift knobs. I want to use this i know ill have to do some modding but can anyone tell me the size of the diameter of the shift stock? Also what is on the top once you remove the stock knob? Can you thread the stock if it doesn't have threads for thread on knobs allready?

 

The factory knob is just pressed on, most aftermarket knobs use a set screw to secure it to the shaft. Put a big crescent wrench under the knob and hit up on it with a hammer and it will pop off. Be careful not to hit yourself in the face.

 

Yes i know thats how to get it off but this Budweiser shift mod i wanna do is 3/8 would that fit on or no? I know id need to find a way to secure it but i wanna see how big the shifter stock is first to give me an idea what im working with. Anyone else done anything like this?

 

Try measuring the shaft, it is not tapered or anything. I would bet it is larger then 3/8" though.

 

If it's larger then 3/8" you could cut it flush after removing it and drill it to accept a 3/8" shaft

Actual size is 0.580", about 37/64; closest to 9/16 or 0.5625". There are NO threads on the shaft, just a notch and a flat area to accomodate the standard POS knob. The T-case shift lever is the same design, but closer to 7/16 diameter with the same notch and flat area. Both knobs are press on, pop off style - and they are known to rattle.

Once you pull your stock knob and see the design, you will likely conclude that you do NOT want to modify your stick shift lever with threads. Rather, you might want to consider drilling out the new knob to slide onto the shift lever itself, and affix it to the shift lever with an allen head set screw. That would require you to drill a small diameter horizontal hole into the new knob and thread it for the set screw. The set screw would engage the notch on the shift lever. Makes it real easy to change your mind or your shift knob later too.

This is how Drake does it with their aluminum replacement knobs, and it works extremely well. Anything else is a PITA, imho.
