How much are they charging you for a rebuild? The reason I'm asking is because my '66 Crown Coupe has to be towed to the shop & I'm wondering if its going to be better to have the engine completely rebuilt at this point (I'm not sure what's wrong with it but it doesn't sound good).I live in St. Louis so the prices my be different, but it would give me an idea of where prices range. Thanks for your help, Loyal Stern
