Loose pickups workaround?

[E_sharp_its_not_F]

Hi everyone how's it going?
Last year I replaced the stock pickups of my telecaster (Squier Telecaster Custom the one with the humbuckers, [no P90, either Widerange]) and after changing them I noticed they're quite loose (At the point that when I play some bass notes they phyisically vibrate). *I attached a stock photo of my guitar bc I always have troubles trying to find the model; I don't know the exact name)

So my question is:
How can I assure them without replacing and ordering a custom pickguard? Is there any DIY way? I mean using clay(?) or something like that? I'm going to open the guitar and I want to change the pots and I wanted to also fix this issue.

Thanks anyone who take the time to read this
Hope everyone is doing okay with the pandemic <3

Have you got springs or rubber tubing over the pickup screws?

Probably well positioned extra rubber tubing, or similar. Under or on the sides of the pickup?

@Lowerleftcoast @AAT65 Sorry I metion you two because you asked me the same; the pickups are loose on the sides I checked it because the pickups balances in its sides when I move them

Cut a piece of polyethylene foam packing material to fit beneath the pickup. You don’t need a lot. Just enough to fit under the adjustment screws. Use the height adjustment screws to drive the pickup down into it. One source of the foamed PE is the packing inside the box a computer is shipped in. Don’t use styrofoam. It crumbles and leaves dust.

Soft foam rubber etc under the pickups
Larger diameter more robust springs.

Foam under pickups will work.
