A lot of guys just install new modern capacitors under the chassis and leave the originals in place but electrically disconnected. If you want to get fancy you can disassemble them, pull out the guts and stuff modern parts inside them, usually new capacitors are smaller and can fit in the old can.
Irrc, on some Tek 400 series scopes, the PCB uses capacitor negative tabs for trace continuity. Not a problem, but you do need to check and, if necessary, jumper the pads to maintain continuity.
I've made adapter PC boards then foolishly realized the new snap-in cap has 7.5mm or 10mm lead-spacing and can just fit right on the main board between two (old) pins. Try measure it. I add jumpers if required to join the extra case pins.

Problem is the caps have individual cut outs on the chassis which they go through although one pin will line up the other wont
Good information to keep in mind but it's not a Tek scope it's a valve amplifier
