In that case find the transistor heat sinks that look like these, drill
them out to fit the plate cap and ...you're in business.
If I'm not mistaken you can purchase this material (extruded Aluminum

you need to be able to cut and drill them out while leaving a nice
finish and a hack saw will fail that test.
