Blank carts/carts on atties - the same?

[SailCat]

Do the empty carts for 510s and 901s and the empty cart/mouthpieces that come on some models of atomizers share the same internal structure (other than the latter having no filler material)?

In other words, can I place filler material in the blanks that come on atomizers with the same results/performance as with the blank carts I buy? I notice in some cases there is a slight difference in length.

An extensive search didn't reveal an answer.

Yes, they are the same cart bodies, with the same internal structure. The ones that come with attys only need some filler material, or else they can be a drip cart without filler, but they are the same cart bodies as those that come with filler, prefilled or not with juice.
