Tru,
Congratulations on getting the heads back and now being to the point that you can start putting things back together. You should have it ready to go by the first snow.
As for the Coupe, it will be delayed if that is the rear main leaking as it is quite a job to get to it the way the car is built. If I remember correctly, the front end has to be removed and then the motor and tranny removed together. Not a simple job.
