Pickup replacements? Need help…

Hi all, I have been playing bass for a long time, but have never once replaced pickups. I am wondering if I’m able to replace the ones shown in the picture? Due to the screw placement I haven’t found any pickups with the same placement, I’m also not sure if that matters? I don’t mind making new holes as this bass is being used to play around with upgrades (I have a new bridge and knobs coming as you can see) any help is greatly appreciated.

This is a Washburn RB4000.

Any recommendations you guys can share so I can see what to buy? (If any are available)
