You caught me just at the right time for this question. I am doing a short shifter swap in my RX-7 tranny which happens to be in my B2200. The shifter is pretty much the same between the two. I have taken a few pics too, since I know everyone here hates pics and info. . First is the stock shifter. I just pulled it out so its a wee bit greasy. Next is the shorty next to it. The sort shift is accomplished by increasing the length of the lever. An additional couple pieces are needed to get this done, but as you can see this leaves a nice threaded end for someone to adapt any shifter they want to onto the harder end to fabricate of the two ends. Last shifter pic you can see a bit of engineering went into these shifters so unless you have access to a machine shop and have the skills to tackle this job, the shorty option is probably easier and cheaper. I paid $30 shipped on Egay.
Also make sure you replace these boots if they need it(And they do). I know they are pricey($90 for all 3), but you don't want those exhaust fumes sneaking into your cab, or tranny lube sneaking out of your trans. -Ed
