I had a member PM me regarding Hurst shifters so I thought I would go ahead and post up a few pictures of the lever differences and some other minutia. Here are two factory shifters. on the left is a 70-72. The one on the right is a 68-69 If you look closely, you'll see the levers are different. The 70 and up shifters have notches cut into the holes to accept a rubber bushing- GM#1234418 which are readily available. Here's what they look like- The earlier shifter takes the common white nylon bushing that is available in the Hurst "Pit pack". The shifter handle is a push in/ bayonet style. There is a notch cut in the left/ driver's side of the handle that locks it into the receiver- And if you look into the handle receiver, you can see the stainless clamps and rubber isolators. If you look closely you can see the corresponding clip on the side of the clamp that clicks into the notch in the handle. In order to remove a handle, you have to slide a feeler gauge between the clamp and the handle down far enough to depress the clip. Sometimes easier said than done. They sometimes put up a fight. And here's a bit of trivia- Hurst shipped their shifters with a round Hurst decal covering the center pin so it wouldn't fall out. Although it says "remove before installation" hoe many line workers just jammed the bolt through and tightened it down? And here is a gratuitous pic of the 70-72 shifter I just rebuilt. Came out sweet! Next one I rebuild, Ill post up a tutorial. They aren't that bad to do.
