I'm at the point in my ghia rebuilt that i need to get the engine seal rubber and the firewall seal rubber for my ghia. I want to get the best I can as im not doing this a second time. I know there are a number of companies making them but which fits the best?

West Coast Metric, there are many cheapo rubbers out there and many are bad news.
