Bought Bob's kit and installed them in my 1981 Heresys in June of 2019.  I didn't cut any of the leads when I soldered them but they'll have about 1/2" removed on each side when I remove them.  Will include the mounting blocks and possibly the zip ties that come with the kit depending on how easily the zip ties can be removed.    The kit is $57 shipped from Bob - selling mine for $30 shipped.  Send me a PM if interested.
