MA WTB Oil fill tube bolt. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

As the title states I’m looking for a factory bolt that bolts through the manifold and has a stud sticking up for mounting the oil fill tube.

Thanks
Mark

I have several stud bolts but not sure what the needed thread and bolt depth would be. If you can supply thread size and grip length of the bolt I can check my stud bolts to see if any are correct for you need.

Since I don’t have one I cannot offer that information. But I’m sure someone here will speak up if they see this.

Thanks

Mark, sorry can't be more helpful with the correct stud bolt your looking for. I have about half a dozen of various sizes which '' might " be correct but have no information for the needed size. Hopefully someone can chime in here with the right size your needing.

Mark: here is pic. of the one on my 71. 3/8" bolt, 15/8" long, 1/4" spacer, flat washer, lock washer. Hope this helps you.

I could’ve sworn the ones I have seen for sale with the oil field tubes were a bolt with a stud sticking out of the top? I believe it was done like this so that you do not have to loosen a manifold bolt if you need to remove the oil fill tube. I do not know for sure so I’m hoping someone with more knowledge than myself will chime in.
