72 Side Louver Nut

[Michael C.]

Asking for a friend - Does anyone know what are the thread specs for the nut for the "stud" holding the bottom of the front side louver on a 72? Apparently 1/4" is too large and a 10-24 is too small. Not a speed nut.

Thanks
Mike

Re: 72 Side Louver Nut

I looked up the GM part number, and Paragon sells these as part 15065K, GM part is 3857243.

FYI they are a PITA to install.
I ended up leaving it off the car because they've been off for probably 30+ years and it has done just fine.

Thanks for the reply Patrick. I saw the kit (11364K) at Paragon and elsewhere, but hoping to avoid paying $7 + $ shipping for a couple nuts.

I see that the number you provided is for a windshield wiper arm transmission nut kit. I might have an extra one of those...around somewhere.

Thanks

Re: 72 Side Louver Nut

It should be a #10. Don't remember if it is 10-24 or 10-32. Unless somehow the stud has been changed.

It's the same part number, and was used on various locations of the car.
You can Google the GM number and see what you can find.
I just added the part to an order I already had going so no extra shipping.
