There has been a lot of discussion about how to shorten the Supra shifter without spending the money for a C's one.  Many just break the upper and lower halves apart, discard the upper half,  and install an aftermarket knob onto the lower half.  This is a sure way to get a very short shift, but some have complained about how noisy it was.  I decided to see how short I could make mine while keeping the insulation between the upper and lower halves and the stock knob.

Breaking the upper and lower halves apart did take some effort.  I cut the top half down to where the big part is about 1 1/2 inches long.  The lower part I cut to just above where it gets its narrowest.  I could probably have gone another inch off the top and half inch off the bottom, but that would have put the roll pins awfully close together.  I then pressed the two halves back together.  I drilled one hole all the way through the two halves near the bottom of the joint and installed on pin.  I then drilled another hole near the top of the joint perpendicular to the first for the second pin.  With that done everything was reinstalled. 

1- Getting the halves apart in the first place can be a real bear.  I had friend of mine do it at a machine shop.
2- Cutting the halves off straight and without a lot of time requires some power tools not everyone has access to.  I sure wouldn't have wanted to try this with a hacksaw!

1- The roll pins I bought turned out to be about 1/16 of an inch short of going completely through the shifter.  Maybe getting longer pins and cutting them off to length after installation would have been better.
2- My rubber seals were tore up pretty bad and I will have to separate the two halves and re-pin them once I get to seals. 
3- The nylon ball on the bottom of the shifter was completely gone.  I have been told that it just disintegrates over time.  I got the green truck shifter ball from Jay Marks Toyota.

There is a slight vibration felt in the knob, but no noise.  The shifter is about 3 inches taller than it would have been had I just separated the halves, but I could probably make up another inch and a half of that with different cuts.  The added height was worth it to me to retain the sound insulation and stock knob.
