This specific cap you have is the easiset type to restuff.
I usually cut it at the upper border of the depression (groove) such that the narrow part remains with the sawn off bottom.

I did use pipe cutter, but this is not the best as it will mush the cylinder a bit, especially at the end of the cut: this is the tool to cut thick copper, not thin aluminum. Again, it will cut, but much more accurate cut could be obtained using regular hacksaw.

I have several threads where I showed the way I did it.

This is one of them, though the caps are with caps on top, not the one you have; still the stuffing is similar.

This is a similar to yours type, though 2-section one.

The latter one shows the same body type, with the depression.

There are two ways of handling it for me,

1. As shown in the latter link pictures, I use a piece of plastic pipe, and epoxy the two parts together onto that pipe. You have to make sure your new cap fits in it.
2. I take a pair of dykes, and neatly bite into the remnants of that depression and push/twist the leaflets (formed by biting) inside a bit, so they would fit inside the remaining piece of the old cap; then smear some epoxy at the inner surface of that remaining piece and push the lower part into it, straighten it out and leave to cure the epoxy. Oh, and I put a fishpaper cylinder inside to insilate that new cap from the old case.
The depression will become a narrow groove but will still look fine, and in many cases will be consealed by that cardboard sleeve, that the cap fits into, anyway.
