In my experience, it depends. I have a newer gold ash assembly that I took off a banged up kettle. Unlike the old version (think SS Performer or older MTs/Golds where the ring is attached to a bar and is used in conjunction with the 7409 sweep), it uses the 7444 sweep. On the newer gold ash assembly, the ash ring snaps into the holes of the leg sockets. What I have found is the new ash assembly ring tabs don't line up with the socket holes on the older kettles.
In short, if you have a newish kettle, you can just get the new style assembly and put it on. If you're trying to take an older kettle and want to turn it into a gold, it might not be so straight forward. Now, YMMV. I don't know that all newer kettle sockets are aligned the same way. Also, if you do have an older kettle, maybe by chance the sockets will line up? I don't know. I know I've tried 2 of my older kettles (80s) with the new style gold assembly and neither lined up. I then tried it on a DZ (2008) kettle and it fit perfectly. I have no idea if the socket hole placement is standard and if it is, I don't when it happened.
If you have an old style gold ash assembly (with the cross bar), all you would need is a 7409 sweep and you're good, no matter what vintage kettle you have…..I think.
