The L34 production breakdowns that I've seen are:
'68 - 234
'69 - 1,947
'70 - 1,802
TOTAL - 3,983
The L78 number is around 9,383 units total for those three years (68-70).
You can usually find one that is supposed to be a factory 396 car.... the fun begins (as we've talked about at length on Steve's Nova site) is determining if it is a factory BB car, or finding one that still retains the original drivetrain.
