Its a different world out there today. Spent to many hours trying to explain it to people over the phone. A visual aid with some explanation sure helps.
Yes, a good explanation. Don't exactly agree with this being moved to off-topic section. But it ain't my website. I just wanted to add that I used several studs in the pan rail to be used as locaters when installing. It worked really easy for me. Although my street TBird doesn't need to have the pan pulled as much as a race car. I have to say again, Mummert did my y-block G iron heads years ago before the aluminum heads were on the market and they are still working fantastically!
