I think Ocean State Electronics has the same tuning capacitor Jeff and I used successfully.http://www.oselectronics.com/ose_p59.htm It is item BC5G at the bottom right corner of the page. It's a nice solid little capacitor with ball bearings. The only pitfalls are the threads are metric (I found screws for it at Sears Hardware) and you must fashion the mounting ears.
