What is the shift pattern for SM420? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**georgieb51** · 02-02-2022, 04:22 PM

I am restoring a 67 short K10 that I got as a pile of parts . The SM420 is installed but I have not had the truck running and will need a shift knob soon (since I could not find one in the pile of parts). Just wondering if the shift pattern is different from later 4 speeds. I realize I can just try to shift it while standing still and see what I get, but maybe someone just knows the answer. Then I will go next door and ask about buying the right knob.

1 through 4 are in a normal H pattern. Reverse is towards the driver and down.

I've got this original knob out of a 67 with an SM420. It's yours if you want it.

That would be wonderful. I have bought things from you in the past. I cannot remember what right now but I remember your name. Let me know what I should be sending you for $. Thanks, George

Just cover the shipping, and I'll send it your way. Let me look up how much that will be.

Thanks for the gift of the knob. I also admire the 67 glove box door you have in the photo. I finally tracked down one of those this year too. So many 67 one-year-only parts.Attachment 2164806

I'm jealous of the truck. Looks great! I'm hoping to find a K20 to rebuild at some point.

pjmoreland, That was very nice of you. Not many people like that. Most just want sell and some want an arm and a leg.

Thank you, BigBird05. I pulled all of the clutch parts off that '67 truck at a pick-n-pull yard. I had a pile of miscellaneous big and small parts. They didn't even bother charging me for the small stuff, including that shift knob. I didn't need it, but I grabbed it anyway. It makes me happy to see it go to good use instead of languishing in a box in my garage.
