[NSRCA-discussion] Motor Mount Bonding

[Bob Richards]

There used to be a great hobby shop in town, but people did not want to buy from him because of his attitude towards the customers. I now make a trip once a month to KC Hobbies (1.5hrs each way) since they have good inventory, and the people there are super nice.
   
  Oh, I'm sorry, we were talking about engine mounts. :-)
