Subaru 5 speed Shift Knob w/ shift boot holder

This is a shift knob for any 5 speed manual Subaru's or any vehicle with a M12x1.25 thread. I also added on the original shift boot adapter piece from the oem shift knob to hold the leather boot to the shift knob. Also includes a simple shift pattern on the top. The dimensions are 97.4 mm tall, 50 mm diameter tapering down to a 33.64 mm diameter at the bottom. The internal thread length is 26mm. I plan on re-designing this shift knob but with the capability to add weights to the shifter. I also recommend finishing the knob by sanding/painting or any other methods for the best look. Any tips are appreciated. Thanks.
