Re: Straightline 4-speed shifters?
A buddy of mine had one of these in his '70 Camaro back 20 years ago. To shift into first you had to stick your first two fingers into a mechanism, lift and push the shifter forward into first gear. From then on, it was pull straight back into 2nd, push into third, pull straight back again into 4th. Reverse was a seperate lever. There was no way to go from second back into first without using the finger mechanism.
You could really preload the shifter and then just touch the clutch and it would shift. Trust me, they will take abuse. That is probably why ET times went down.
