Apart from some teflon wire (thanks again Pete), Mouser had most of what
I needed. Unfortunately, they no longer carry said heatsink. Thanks
though. Other ideas ??

===================================
For large heatsinks (perhaps not precisely the type you need ) flea
markets will be a likely source . Otherwise there might be an
electronics surplus store in your area .
Some time ago someone gave me a clapped-out (probably illegal) CB
amplifier (of Italian origin) with a heat sink to suit your project
.........however I am in Scotland- UK ,otherwise I would be happy to
send it to you .
