So I'm fixing a broken jack on a Hartke lh1000 bass amp.

Original broken jack:

I've looked everwhere online and all I can find is this one:

So they look pretty much the same except for the metal sleeve on the original. The amp I'm fixing is a hartke and the website says this part is for hartke amps.

I'm not sure, does that metal sleeve actually do anything different?

Do you think it will be fine using this?
