Request for RECOMMENDATION on needed size of bottle jack

[gregorydh]

Due to a misunderstanding about the intent of my previous post, I am reposting this question.

My '72 Chevy C10 did not come with a jack for changing tires, etc. I intend to acquire from a store a new generic bottle jack to carry in the truck, to replace what originally came with my truck but is no longer with it.

What I am looking for is a recommendation on the size of bottle jack I need. I am not asking anyone to provide me a jack, and I am not asking where I could acquire an OEM jack. I would simply like to know, in the experience of people on this forum, how big of a bottle jack do I need? I'm primarily concerned about needed lift height, so that I can get a front or rear wheel off the ground to change a tire using the recommended jack points. My suspension is stock, with no fancy wheels or large tires.
