I will never buy a kit exhaust agian. I bought a flowmaster kit for my 67 but the kit was for a 66. I called flowmaster and they told me it would fit the same. It did, but I never want to try to put one in agian. Way to much work to many headaches. It would have been easier and cheaper on me to take it to my local exhaust shop. I never got the exhaust to seal correctly untill I took it to the exhaust shop.
