That had to be awful!As a long time Pontiac Owner/Fan I can appreciate the work.
I've replaced a few of those "Rope Type" rear main seals in my day.............Once in the middle of winter, in the driveway of my Parents' house in NY, underneath the Car when it was 10-degrees F outside!
That was fun.....................
Love the Car!
I once helped my dad replace a starter in a snowstorm in the grocery store parking lot. As a 10 yr old the best help I gave was building a snow fort wall in front of the car to block the wind.
A new neoprene seal is going in.
