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 
heat sink) at a bit less than $45 for a several foot length. Of course 
you need to be able to cut and drill them out while leaving a nice 
finish and a hack saw will fail that test.
