I think up to $15K for quick sale is do-able. There are 'S' engines and cases available from time to time, though they will not be 'numbers matching.' Assuming Albert Blue was the original color and that the paint looks as good close up as it does in the pictures, you have a desirable car.

You might consider buying some time with the car by swapping the engine for one in better shape just for a year or two while you search out an S engine and proper interior. That way, you can enjoy it in the meantime.
