I am custom making a shifter handle for a slap stick shifter and after seeing this post got the ambition to try to make my own pistol grip. It is by no means factory, but hey I am making the whole handle myself so it doesn't really matter. Anyways just wanted to post a pic of it and thank everyone who posted pics earlier in the thread...I used them as a guide to make my own. It is made out of Walnut by the way. I carved it with a 90 degree angle grinder with a 3 inch sanding disc...took all of about 2 hours to complete. now I need to make the metal arm to hold it to the shifter and a way to engage the push button.
