Get some shim stock. Cut to a size that will allow you to press the bearing in with reasonable pressure.

If its not that loose use a punch and dimple the surface {raising it} enough to fit the bearing, with reasonable installation pressure.

one idea i had, too, was shimmin it
some cheapo feeler gauges might be in order

There's an industrial supply hardware store near me that has that hobby display of metal sheets K&S I think it is.

Dimpling the inside of the drum is commonly done too.

Look into Loctite 680. It is a gap filling liquid/glue stuff that is specifically for this kind of application. I used it on my loose-ish neck cups. I haven't ridden it yet but the specs for Loctite 680 looks like it will work fine. Thousands of pounds of compressive strength. It has a long working time. You could put the bearing in, install the whole shebang back in the fork, and it will set up properly aligned.

ill look at that stuff

Another thing to check is if the bearing bore in the drum is round or egg-shaped, or if it's a larger diameter at the outside than at the deepest point. If it's wallowed out, you might need to consider boring and sleeving it.

havent got to measuring it yet
hopin that is not the case tho

I'll keep my fingers crossed too.
If it is, now's the time to correct it. Locktite is a good fix but often temporary.
If there's any movement, it's not gonna heal itself.

Smart. I've got Sportster drums front and rear on mine and ended up going out of town for the last of what I needed.
