[Survivor 69/Z28]

Gear Jammer is a very good friend of mine and we are both going to look at the car first thing in the morning. I am familiar with the Chevy's but not at all with Pontiacs. Are the casting #’s on a Pontiac motors basically in the same locations?
How about the rally wheels? Are these date coded like the Chevy's? I have the #’s for the quadrajet. If the carb has been changed are these hard to locate compared to others?
Anything you guys can think of that we need to go over on this car please let us know.
Maybe there are some certain parts on a 69 goat that are hard to find. Well, we want to make sure that this car has it so that we can make a decision soon.

Thanks for the help!!
