Accurate Exhaust Products?

Guys:

Thanks for the info. I think you've helped me make up my mind. My car is almost entirely original and 100% numbers matching (except for the tires/wheels), so I'd really like to stay with a factory look. It still have the original head and tail pipes, and they're getting kind of old and crusty.

I need to check the exhaust manifold casting numbers for my 73 340. According to the Accurate website, the casting numbers for my model are driver side: 3614368 and passenger side: 3418623. But according to the Mymoparts.com website, the driver side casting number is 3614395. That makes me wonder if Accurate has a system that will fit my vehicle.
