Even though we presently show knob selections for Hondas and Corvettes only, we can provide custom knobs for many other types of vehicles. In order to do this, we need to find out a few dimensions from your factory shifter/knob combination. In order that you can easily see which dimensions we are looking for, we have created a PDF drawing of a typical shifter/knob (exploded view) assembly.
Please click here to view the drawing and the required area measurements. Keep in mind that some shifter shafts are tapered so that the threaded (top) section is smaller in diameter than the lower section. Because each of our shift knobs (for manual transmissions) require a locking collar, the clearance hole in the locking collar must be large enough to accommodate the diameter of the shifter shaft at the height where the bottom of the factory shifter normally resides. Please call or e-mail your measurements to Dave at 858-733-0171 or sales@conceptualpolymer.com.
Since each of our shift knobs is threaded specifically to your shift knob's internal geometry, you will never have to worry about flimsy threaded inserts (common to many aftermarket shift knobs) failing at the worst possible moment.
