Trying to identify a fluorescent fixture

[kk7xx]

Hey guys, we are moving and I'm trying to fix two T12 4-ft long 4-lamp fixtures that seem like the ballasts are shot before we list the house, neither turns on without flipping the light switch on and off a few times and then one of them flickers nonstop.

We have a weird setup where the fixture is riveted above the drop ceiling and one of them is in a tight spot between ductwork. I can't seem to find anything like this online or in stores, was hoping someone here might know where to look. Does anyone recognize what these fixtures would be replaced with?

They show UL E-76333 but that code doesn't return anything in the UL database.

Thanks in advance.

just buy replacement ballasts, or remove the ballasts and replace the bulbs with led

Thanks, I will look into replacing the bulbs with LEDs. Looks like there are some good videos on YT showing how to convert the fixtures, good thinking.
