Sorry to read of your Mopar mentor passing Al, way too young. Great news with Dr. Diff! Ive been contemplating an "upgrade" on ours from 323's up to 355's. If you dont mind how "bad" were the shipping costs?
About $ 240.00 US . For a very heavy reinforced box (Great job packaging it up Cass!!). Remember, I'm on an Island on the Far East Coast. You will be a lot less in Ontario so should be much cheaper for you. Shipping/Customs pricing for me is outrageous but what can you do? If I want the parts , I have to suck it up and pay.
BTW, Thanks for the condolences for John. He waqs such a great person, always willing to take the time to share his extensive knowledge in a way you could understand. Guys like him are becoming scarcer every day.
