These are factory shifters. The one by itself on the bottom is not factory. The 4th one from the left is the factory A body one used in 68 and up A body cars.
shim your shift rods so that they don't wiggle...that and a comp plus will have it shifting like a Porsche. A lot of the movement is rod deflection. It takes some time unless you have teeny weenie really flexible hands.
I have an assortment of shims and clips that I gathered to do mine.
I may try this first maybe I can sell the shifter assembly I have now and buy a competition one also there is quite a bit of play in the shifter as well
What kind of shims did you use ?? Have any pics and where to get em thanks
