When I converted my 87 Diplomat over to 4 speed I rebuilt the A833, new Hurst Comp shifter. It was smooth shifting, two fingers is all it took. Taught two of my daughters how to drive stick with that car.
I did take the shifter apart, smooth any burrs, light polish on the shifter levers, clean, grease and reassemble. Nothing magic, just a once over.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
