hello from New Zealand, 18 spline head ache a833.

Aggressive in my box, is to make the decision to shift, and then "blam" it in there. I still clutch it, even at WOT, Cuz you know, I'm not too excited about repointing the teeth during the Summer, when I just want to drive. With mine, I found a short stick really helps with the "blamming"; and I don't run much free-play, nor much clutch departure, so it doesn't take much pedal to disconnect.
If yur running a standard shifter in an A-body, on the short-tail trans, with a Tee-handle, you gotta know a few things;
1) you better loc-tite the Tee-handle down so it will never move, and
2) cuz if it moves, your knuckles will most likely be headed for the dash on the 2-3 shift, and
3) if they are not, then you're not being aggressive enough
lol.
for this reason;
4) I run a ball on the shifter, cuz it hurts less when the stick hits, the stop. but
5) I no longer run the shifter in the factory position. I installed a long tail, and relocated a short stick to about 6 inches to the rear and snuggled it up to my thigh. Then fabbed up some stout shifter rods.
Since that day, I have never missed a shift, even at 7200.
