Are all slant dip sticks the same length?Where to get one?

I have a 1977 Ramcharger with a Super six in it/ original that I need the dipstick insert not the tube. All the ones I see on ebay have the tube and they want a fortune for them.

I am guessing all slant six are the same but thought I would ask?

Also, currently is has a one barrel manifold and carb on it. I believe the original stuff was removed for a car years ago. How hard is a manifold and carb to come across and what do they typically cost and is it a good HP difference?



any idea where to Get the insert at a decent price.

Thanks LAWFISH.
