I was tired of shifting my "big truck" shifter. I like the position of the shifter, but i don't like the length. Yeah,Yeah,Yeah, I know you can buy shifters online, but they all lose the dog leg, which i like.
...... so I took it to a few machine shops around town....
They wouldn't touch it, either because I wanted to keep the dog leg, or because the threads are metric...doesn't matter, i lose both ways. One machinist suggested I get a die and run it down past the original threads, then lop the shaft off where i want it.....so that's what i did!
Now, the shifter sits perfect, still looks factory (better than, imho), and the shifts feel MUCH better!
1) You'll need a Fiero with a manual transmission and original factory shifter.
2) a 16mm die with 1.5 thread pitch to cut new threads.
3) a hack saw, or better yet, a saws all!
4) a vacuum (to clean up the mess when finished

)
