Ah yes! 1-2 & 3-4 shifts in my '57, my '68 Chevelle and my '68 Corvette. 2-3 in the '57 could happen too with the Hurst Comp+, but was a definite No-No with the other two and their factory linkage.
2-3 shifts in the Chevelle could be timed with a calendar.
We also damaged a couple of T-10 crash boxes.
God, to think about the stuff we trashed back then.................
Today, it's not just about the $$$, it's also about the scarcity of those parts.
