Congrats on the '70 W30...is it a post car? .
I bought a '70 442 Post car in Toronto about 25 years ago and drove it the hour home down Hiway 401 w/ a dealer plate flapping, a leaking gastank and no brakes! .
Obviously foolish now but seemed to make perfect sense back then...even took it up over 100 mph on route! .
