Welcome here Rat Patrol. Good to see new guy here, specially from way down under. Lots of very good & knowledgable guys here ,but what I found is guys visit here on occassion,. so give them time. The person that would of gone one on one with you on this project, Paul Ceasrine, unfortunately passed away recently. He was the most knowledgeable person I knew on stats etc on thi8s stuff. He was instrumental in helping me finding the history on my car, & also turned my thread into prolly the most visited one on the internet today. Well over 1,000,000 visits.
